—We present a monographic treatment for the 13 species ofElaphoglossumsect.Polytrichiasubsect.Apoda(Dryopteridaceae). Molecular phylogenetic analyses have recovered this subsection as monophyletic within the so-called “subulate-scaled clade” ofElaphoglossum. Morphologically, the species ofE.subsect.Apodaare usually characterized by the presence of brightly colored stem scales (yellowish, orangish, or reddish, as opposed to castaneous to black), evenly distributed subulate scales on laminar surfaces, tiny glandular hairs on different parts of the leaves, and adult sterile leaves without hydathodes. The species can be divided into two groups: one with subsessile and the other with long-petiolate leaves.ElaphoglossumsubsectionApodais distributed from southern Mexico and the Antilles to Bolivia and midwestern Brazil.Elaphoglossum atehortuae, a new species from the Amazon region of Ecuador, is described, illustrated, and compared to its most similar species. It is unusual within this group for lacking subulate scales on both surfaces of the laminae, a character state that it shares withE. backhouseanum. Two species,E. polyblepharumandE. trichophorum, are included in the group for the first time, whereasE. procurrensandE. siliquoidesare excluded based on morphological characters and previously published molecular phylogenies. We also provide comments forE.×morphohybridum, which is a hybrid betweenE. alvaradoanumandE. crinitum. Lectotypes are designated forAcrostichum apodum,A. platyneuron,A. cubense,A. procurrens,A. trichophorum, andElaphoglossum auripilum, and epitypes are designated forA. apodum. To facilitate the identification of species, we provide keys, descriptions, illustrations, comments, synonyms, distribution maps, spore images, and a list of specimens examined.

To mark the commencement of his retirement as Nathaniel Lord Britton Curator of Botany, and appointment as Curator Emeritus at the New York Botanical Garden, we pay tribute to Robbin Moran and impact on the botanical community with a brief synopsis of his career. Naturalist, fern expert, adored teacher—it is difficult to adequately pay tribute to his accomplishments, and his impact on botany in a single article. Robbin has published four books, 13 monographs of neotropical fern clades, over 170 scientific papers, and dozens of popular articles. He has named 115 new species, five new genera, and one family of ferns. He is eponymized by seven new species and the genus Moranopteris. We recount his earliest days and academic trajectory to become a leading researcher and educator in pteridology. We highlight his major influences, scientific accomplishments, and outreach to the botanical community.

We found 204 species of pteridophytes in Reserva Natural Guaricica, a private natural heritage reserve (RPPN) in Antonina, Paraná, Brazil. With approximately 8,600 ha and elevations ranging from sea level to 600 m, RPPN Guaricica has more species of pteridophytes than any other area in Paraná. Ferns are represented by 194 species in 82 genera and 26 families, whereas lycophytes comprise 10 species in four genera and two families. The RPPN is the type locality of two recently described species: Hypolepis acantha Schwartsb. and Oleandra australis Schwartsb. & J.Prado. It is also the only place of occurrence of Didymoglossum angustifrons Fée, Diplazium riedelianum (Bong. ex Kuhn) C.Chr., Pteris ensiformis Burm.f., P. tripartita Sw., Saccoloma elegans Kaulf., and Steiropteris polypodioides (Raddi) Salino & T.E.Almeida in Paraná. Pteris ensiformis and Saccoloma brasiliense (C.Presl) Mett. are new state records. Additional species are expected to occur in the area, in view of their known geographical ranges.

We present a taxonomic treatment for the species of Didymochlaenaceae and Dryopteridaceae occurring in the region of Viçosa, Minas Gerais, Brazil. This study was based on 50 herbarium gatherings from IAN, K, NY, PACA, RB, SP, UPCB, US, and VIC. Didymochlaenaceae is represented by a single species, Didymochlaena truncatula, whereas Dryopteridaceae has 11 infrageneric taxa in seven genera: Ctenitis (four taxa, including two varieties), Megalastrum (two species), Mickelia, Parapolystichum, Polybotrya, Rumohra, and Stigmatopteris (one species each). Among the 12 infrageneric taxa here recognized, seven are endemic to the Brazilian Atlantic Forest. Ctenitis distans var. isabellina, Megalastrum connexum, and Polybotrya speciosa are here reported for the first time in Viçosa. Identification keys, descriptions, illustrations, geographical distribution, and comments are presented to all taxa.

Part of this biodiversity is within protected areas. The development of online databases in the last years greatly improved the available biodiversity data. However, the existing databases do not provide information about the protected areas in which individual plant species occur. The lack of such information is a crucial gap for conservation actions. This study aimed to show how the information captured from online databases, cleaned by a protocol and verified by taxonomists allowed us to obtain a comprehensive list of the vascular plant species from the Parque Nacional do Itatiaia, the first national park founded in Brazil. All existing records in the online database JABOT (15,100 vouchers) were downloaded, resulting in 11,783 vouchers identified at the species level. Overall, we documented 2,316 species belonging to 176 families and 837 genera of vascular plants in the Parque Nacional do Itatiaia. Considering the whole vascular flora, 2,238 species are native and 78 are non-native. New information The Parque Nacional do Itatiaia houses 13% of the angiosperm and 37% of the fern species known from the Brazilian Atlantic Forest. Amongst these species, 82 have been cited as threatened, following IUCN categories (CR, EN or VU), seven are data deficient (DD) and 15 have been classified as a conservation priority, because they are only known from a single specimen collected before 1969.

Background – Cyclodium is a neotropical fern genus comprising about ten species. Most species are found in northern South America, and the foothills of the Guiana Shield is an important region for species diversification. Our phylogenetic and taxonomic studies of the genus demonstrated the need to describe a new species and to recognize a variety at species level.Methods – This study is based on herbarium specimens from CAY, HUA, INPA, MBM, NY, P, RB, UC, UFP, UPCB, and US. Morphological characters were analyzed using standard procedures. The indumentum and spores of the new species were studied using a scanning electron microscope. Species delimitation is proposed based on our preliminary phylogenetic studies, as well as on morphology and geographical distribution.Key results – Cyclodium alansmithii Bohn & Labiak is recognized as a new species, described, and illustrated. The most similar species is Cyclodium inerme (Fée) A.R.Sm., from which it differs by ovate-lanceolate and bicolored scales, reduced fronds, truncate pinna bases, and non-ciliate indusia. Cyclodium alansmithii is currently assessed as Endangered (EN) using IUCN criteria, but more fieldwork and herbarium studies are necessary to establish a more accurate conservation assessment. Cyclodium trianae (Mett.) A.R.Sm. var. chocoense A.R.Sm. is here elevated to species rank. A key to species of Cyclodium with free veins is provided.

Elaphoglossum Schott ex J. Sm. sect. Polytrichia Christ is characterized by the presence of subulate scales and the absence of hydathodes. We did a molecular phylogenetic analysis using three non-coding plastid markers and found that five species thought to belong to section Elaphoglossum are actually members of section Polytrichia. The five species were previously thought to belong to section Elaphoglossum because they lack the characteristic subulate scales of section Polytrichia. We refer to these species as the Decursivum Group. We assign two other species to this group based on their morphological similarity to the known members of the group. Besides lacking subulate scales on the laminae, the seven species of the Decursivum Group are distinctive by having a submarginal connecting vein, a character otherwise absent in section Polytrichia. The group is entirely Neotropical, occurring at middle elevations and extending from the West Indies and Mexico to Bolivia and southeastern Brazil. For the Decursivum Group, we provide a taxonomic treatment including a key, descriptions, illustrations, distribution maps, discussion, and lists of specimens examined. Lectotypes are designated for Acrostichum miersii Baker and A. papyraceum Fée. A new species from the Andes, E. vascoae F. B. Matos & R. C. Moran, is described and illustrated.

A taxonomic treatment for the three species of Elaphoglossum sect. Squamipedia found in Brazil is presented. The section is monophyletic and most of its species are characterized by slender, 1–1.5 mm wide, long-creeping stems; the presence of two peg-like aerophores on the rhizome just behind each petiole; pale brown stem scales; the absence of phyllopodia and hydathodes; and echinulate spores. Elaphoglossum peltatum is unique among the Brazilian species of the genus by having sterile leaves with divided laminae. Within the country, E. minutum is known from only two gatherings made in the state of Goias, where it grows in gallery forests around 700 m. Elaphoglossum peltatum is found on the mountains of the northern Amazon and disjunctly in eastern Brazil, from 800 to 2000 m. Elaphoglossum squamipes occurs on the coastal mountains of Serra da Mantiqueira and Serra do Mar, where it grows in cloud forests above 800 m. None of the three species is endemic to Brazil. We provide identification keys, descriptions, synonyms, comments, line drawings, spore images, distribution maps, and an index of herbarium vouchers to all species accepted in this treatment. A lectotype is designated for Acrostichum craspedariiforme and a second-step lectotype for Osmunda peltata. Additionally, E. ovatum is here excluded from the Brazilian flora.

In the video transmission of critical urban events, e.g., heart attacks, supported by VANETs, intermittent connections, delays, packet losses, and the number of vehicles in collaboration naturally impair the dissemination of data, and hence affect the quality of received video at the destination. Crowdsensing solutions become a real option in helping to handle these events. In this paper, we evaluate the impact of the characteristics of urban VANETs on the human perception of the spatio-temporal context from monitored videos of critical events. We use the MINUET system to assess the quality of videos disseminated and delivered to city authorities, using QoS and QoE metrics, and under different traffic scenarios. Simulated results indicate the system achieves quality levels from satisfactory to good in most of the evaluated scenarios, i.e. average PSNR values between [25-40]dB and average SSIM values between [0.5-1]. In addition, even in adverse situations for detecting the event, video was delivered with a level of quality sufficient to recognize the event.

A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of Parque Nacional do Caparao (PNC) was previously built using online databases and published on the website Catalogo de Plantas das Unidades de Conservacao do Brasil. Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states. New information Parque Nacional do Caparao houses 8% of the land plant species endemic to the Brazilian Atlantic Forest, including 6% of its angiosperms, 31% of its lycophytes and ferns and 14% of its avascular plants. Twelve percent of the threatened species listed for the State of Espirito Santo and 7% listed for the State of Minas Gerais are also protected by PNC. Surprisingly, 79% of the collections analysed here were carried out in Minas Gerais, which represents just 21% of the total extension of the Park. The compiled data uncover a huge botanical collection gap in this federally-protected area.

We describe Anemia paripinnata, a new species from the rock outcrops of Central Brazil. It is remarkably distinct from most of its congeners by having paripinnate lamina, a character that is only found in the Amazonian A. dardanoi. The new species is described, illustrated, and compared to the most similar species in the genus. The new species is known from few collections in Mato Grosso. Based on the IUCN criteria, it can be considered an endangered species.

We show that Elaphoglossum megalurum, previously thought endemic to Peru and Bolivia, and E. subciliatum, previously thought endemic to Costa Rica and Panama, are later heterotypic synonyms of E. litanum, a species described from northwestern Ecuador. The revised distribution of this species is now construed as Costa Rica, Panama, Colombia, Ecuador, Peru, and Bolivia. The species has a wide elevational range, occurring from (20–)100–1400 m. In South America, it occurs on both the eastern and western sides of the Andes. A complete list of synonyms and their types, a description, specimens examined, and a distribution map is given for E. litanum as recognized in this new, more inclusive sense. A lectotype is designated for E. carillense, which has long been considered a synonym of E. subciliatum, and a second-step lecotype is designated for E. litanum.

Among the Campyloneurum that occur entirely or primarily in the Atlantic Rain Forest of Brazil, three species have been previously referred to by the following six names: C. acrocarpon, C. crispum, C. herbaceum, C. lapathifolium, C. minus, and C. wacketii. We show that C. crispum and C. herbaceum are the correct names for two of the species, and we designate lectotypes for these two names. The third species, which ranges from Brazil to Argentina and Paraguay, lacks a name and is here newly described as C. atlanticum. Two of the previously used names, C. acrocarpon and C. wacketii, are considered synonyms of C. crispum. The remaining names, C. lapathifolium and C. minus, appear to be of uncertain application. Based on our field studies, C. atlanticum and C. herbaceum are primary hemiepiphytes. Our finding constitutes the first report of this growth habit in the genus. The third Brazilian species treated herein, C. crispum, varies in growth habit, being either terrestrial, primary hemiepiphytic, or...

Eventos urbanos emergenciais ocorrem de forma aleatória e precisam ser tratados por entidades competentes para manter o bom funcionamento das cidades. Os principais desafios para um tratamento eficiente recaem justamente na aleatoriedade no tempo ou no espaço, e na rapidez e acurácia da comunicação da ocorrência do evento à uma entidade responsável, sendo este último desafio agravado pelo fato desta comunicação depender de intervenção humana. A onipresença de veículos em ambientes urbanos, sua capacidade de comunicação e monitoramento, possibilitam o uso de VANETs como meio de auxílio para disseminação e tratamento destes eventos. Assim, este artigo propõe MINUET, um sistema de monitoramento e disseminação de eventos urbanos, que atua em uma rede veicular não estruturada. Ele é baseado em uma estratégia cooperativa, onde veículos coordenam dinamicamente o monitoramento e a disseminação de múltiplos eventos em tempo real através de agrupamentos. Resultados no NS3 mostram o desempenho do MINUET na detecção, monitoramento e disseminação em tempo real de eventos em zonas urbanas.

The service interaction provided by objects in IoT networks enables the creation of advanced services to answer application requests. However, the growing number of objects into the IoT network, besides its ad hoc structure, are disturbing some functionalities, such as service discovery. Therefore, when searching for services, the navigability is impaired because the system needs to sweep a great quantity of objects without a previous organization. Social Internet of Things (SIoT) emerged as an alternative to solve several problems faced by IoT through the concept of social networks. In SIoT each object has its own social profile, which contains its characteristics and information, and are organize by relationships. Thus, this research propose a solution for service discovery in a SIoT network. This solution uses the relationships between objects to improve the discovery scalability and considers their social profiles to meet more satisfactorily the requisitions. Simulated results demonstrates the solution performance to answer service requisitions in an urban SIoT network.

The implementation of the Internet of Things paradigm in the most diverse environments is already a reality. One of these environments is the smart hospital that uses several devices to improve patient care and streamline the internal processes of hospitals. However, an obstacle in the use of IoT systems is the difficulty encountered by their user to change devices behaviours as their needs changes. When the users can not update, the system may be outdated. This leads to problems in the hospital which is a critical environment and needs everything to be working properly every time. A way to customize the behavior of IoT devices is the use of police that can be described in high-level programming language. For this reason, this paper proposes a solution that uses policy refinement to assist IoT device management in smart hospitals. The proposed solution was implemented and tested, achieving favorable results for the hospital scenario.

Elaphoglossum mickeliorum, a new species from the eastern slopes of the Peruvian Andes, is here described and illustrated. It belongs to E. sect. Polytrichia, which is characterized by the presence of subulate scales and absence of hydathodes on the sterile leaves of adult sporophytes. Herbarium specimens of this new species were first collected by Alwyn H. Gentry ca. 40 years ago, but these got readily confused with E. erinaceum and went undescribed since then. The new species differs from members of the E. erinaceum complex by having a nearly continuous band of planar, nonsubulate scales along the laminar margins of sterile leaves. Based on this character, E. mickeliorum resembles species such as E. glaziovii, E. ornatum, and E. scolopendrifolium. It differs from these by the presence of minute glandular hairs on petioles and costae. A distribution map and a figure with line drawings are also provided. For comparative purposes, the line drawing includes E. blepharoglottis, which is here illustrated for the first time.

Critical urban events take places at a random way and they need to be dealt with by public authorities quickly to maintain the proper operation of cities. The main challenges for an efficient handling of an event fall precisely in its random nature, and in the speed and accuracy of the notification of its manifestation to the authority. The pervasiveness of vehicles in urban environments, and their communication and monitoring capabilities, allow to employ VANETs to support the dissemination and handling of such events. Thus, this work proposes MINUET, a dynamic system to support the monitoring and dissemination of urban events, which operates in an ad hoc vehicular network. It uses a cooperative-based strategy where vehicles are able to dynamically coordinate the monitoring and dissemination of events in real time by the means of clusters. Results obtained by NS3 show the performance of MINUET regarding the real-time monitoring and dissemination of events detected in urban areas., Comment: This work has been submitted to the Pervasive and Mobile Computing (PMC) journal for possible publication

We present a taxonomic revision for Cyclodium, a neotropical fern genus that is most diverse in the Amazon lowlands, especially in the Guianas and Venezuela, but also extending to Central America, the western Andes and southeastern Brazil. The genus belongs to the Dryopteridaceae and is distinguished from other genera in this family by its dimorphic fronds and peltate indusia. We recognize 13 species of Cyclodium, for which we provide morphological descriptions, distribution maps, an identification key, illustrations and taxonomic comments. Cyclodium pubescens is described as new to science, C. meniscioides var. paludosum and C. meniscioides var. rigidissimum are synonymized under C. meniscioides, and C. heterodon var. abbreviatum is synonymized under C. heterodon. Lectotypes are designated for Aspidium confertum, A. guianense, C. rigidissimum, Dryopteris calophylla and Polystichum inerme. We also provide an assessment on conservation status for each species following IUCN categories and criteria.

Recentemente, uma grande quantidade de dispositivos médicos conectados e sistemas de TI destinados à saúde estão sendo desenvolvidos e integrados para o compartilhamento de dados. Tais dispositivos e sistemas compartilham a mesma rede, podendo ser acoplados a sistemas de monitoramento e análise de dados clínicos. Em decorrência deste compartilhamento, tráfegos prioritários de dispositivos médicos podem ser prejudicados por congestionamentos de rede. Nesse cenário, este artigo propõe uma solução baseada em SDN (Software Defined Networks) para o gerenciamento de uma rede hospitalar através da priorização de tráfego para dispositivos médicos prioritários. Esta solução busca a observância dos parâmetros de qualidade exigidos por cada serviço em um ambiente de hospital inteligente.

Elaphoglossum fendleri, a new species from the cloud forests of Venezuela, is here described and illustrated. The type specimens were collected by Augustus Fendler ca. 160 years ago but had gone unnoticed since then. Some authors have confused it with E. ornatum, a subulate-scaled species that is restricted to the Venezuelan Andes. Elaphoglossum fendleri is also endemic to Venezuela, but it is known only from the Coastal Cordillera and Sierra de San Luis. It is characterized by short petioles densely covered with orangish, flattish, setose-margined scales; oblanceolate laminae with acute apices and truncate bases; and a fringe of laciniate scales along the sterile laminar margins. We provide comments, line drawings, SEM images, and a map of geographic distribution that will help to distinguish the two species.

Cooperation among service providers, network providers, and access providers in the Internet allows the creation of new services to offer to customers that are in other domains, thus increasing revenue. However, the Internet heterogeneous environment, where each provider has its own policies, infrastructure and business goals, hinders the deployment of more advanced communication services. This paper presents a Quality of Service (QoS) for Inter-Domain Services (QIDS) model that allows inter-domain QoS-aware services to be defined, configured, and adapted in a dynamic and on-demand fashion, among service providers. This is accomplished by: 1) the use of a common communication channel (business layer) where service providers publish and search for services, and interact with each other to contract and manage these services; 2) the templates to specify the business and technical characteristics of the services; 3) the automatic composition of services using service elements (smaller services) according to performance and service-specific QoS parameters; and 4) the creation and enforcement of configuration rules for the underlying infrastructure. A prototype was implemented to validate QIDS and performance tests were conducted on an inter-domain Border Gateway Protocol (BGP)/Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) scenario.

Intrusion Detection Systems (IDSs) are signature-based software tools that provide mechanisms for detection and analysis of network intrusions. Using an experimental scenario and real traffic collected at a higher education institution in Brazil, we evaluate the performance of Snort and Suricata IDSs for detection of current Distributed Denial-of-Services attack (Slowloris). Our study has found the IDS Suricata is not a suitable number for alerts to catch the attention of the network manager about the Slowloris attack, while Snort IDS does. Evaluation of CPU consumption and memory of target server. In addition, an analysis of offline traffic reveals that the higher education institution is under DDoS attacks during the analyzed period.

With the growing interest in Smart City using Internet of Things (IoT) the focus in Wireless Sensor Networks (WSN) has increased, and consequently has been used to monitor numerous environments, such as health, habitat control, houses and public transportation. Due this expansion, the numbers of technologies and researches on bus monitoring systems has increase. Thereby, this survey provides information about researches, used technologies, implementation, difficulties and problems on bus monitoring systems.

Most studies on ferns focus on the adult sporophytes, overlooking the gametophyte as a potential source of biological information. Herein, field-collected gametophytes and young sporophytes of Elaphoglossum decursivum are described with the aims of providing a more complete understanding on the morphology of this species and additional morphological characteristics for its sectional classification. Gametophytes share the general morphology of most other Elaphoglossum species, but one unusual observation was the presence of minute scales (proscales) on the thallus. Young leaves differ from the glabrous adult leaves by having papillate glandular hairs. These are the first observations of hairs in the glabrous sect. Elaphoglossum. Our study shows that the gametophytes and young sporophytes of E. decursivum have indument characters that are not present in the adult sporophytes, and studying these life stages could potentially be useful in a phylogenetic context.

We correct a number of omissions and errors in the previous series of publications of the “Prodromus of a fern flora for Bolivia”. Most importantly, we correct the combining authorship for Didymoglossum punctatum subsp. sphenoides (Kunze) Boudrie & Cremers, add missing information on Elaphoglossum latevagans Mickel, and validly publish the new combination and status for Hypolepis rigescens var. buchtienii (Rosenst.) Schwartsb. and new combination Christella abrupta (A.R.Sm.) A.R.Sm., previously called C. grandis, which was invalidly published.

Elaphoglossum clathratum F. B. Matos & R. C. Moran sp. nov. (Dryopteridaceae), which grows at middle elevations on the eastern side of the Andes in Ecuador, is described, illustrated, and compared to its most similar species. It is unusual in Elaphoglossum by having lamina margin scales that are strongly clathrate. Research on the phylogeny of the genus has shown that the new species belongs to Elaphoglossum sect. Polytrichia . However, it is unique in the subulate-scaled clade of Elaphoglossum by having planar, not subulate, scales.

A new species, Diplazium fimbriatum (Athyriaceae), is described and illustrated. It is endemic to the humid montane forests of eastern Brazil, a region known for its high level of endemism and species richness. A comparative table to distinguish it from similar species of Diplazium occurring in Brazil is provided.

We provide a synopsis of the 207 species of Dryopteridaceae in 15 genera currently known from Bolivia. This is the secondmost species-rich fern family in the country and includes the most diverse genus ( Elaphoglossum with 127 species). No fewer than 32 species of Dryopteridaceae are endemic to Bolivia. Elaphoglossum catenatum , a new species from the Bolivian Yungas, is here described and illustrated. We also provide a new combination for Acrostichum papyraceum in Elaphoglossum and designate a lectotype for Elaphoglossum ambiguum . Illustrations for all Bolivian taxa of Elaphoglossum are provided. Taxonomic problems remain in a number of genera, especially Elaphoglossum , Megalastrum , and Polystichum .

Cyathea atrocastanea, a new species of tree fern is described, illustrated, and compared with similar species. This new species should be classified as vulnerable (VU) according to the IUCN criteria. This species is distinct by its atrocastaneous and scurfy petiole, and rachis, and by the broad ovate and yellowish, nonbullate scales on the costulae and midveins. A key to the exindusiate species from southeastern Brazil with nondenticulate petiole scales is also presented.

Asplenium truncorum, a new asplenioid fern from the Brazilian Atlantic Rain Forest, is described, illustrated and compared to the most similar species. So far, it seems to be restricted to the montane moist forests of southern Bahia and Espirito Santo States, at elevations of 750 to 950 m. Field observations suggest that this species grows exclusively as an epiphyte on the trunks of tree ferns, especially Alsophila setosa Kaulf. (Cyatheaceae).

A new hybrid, Micropolypodium xbradei, from Rio de Janeiro, Brazil, is described and illustrated. It shows intermediate morphology between its parents, M. setosum and Terpsichore achilleifolia, in dissection of blades and veins, and number of sori per segment. New combinations for Brazilian endemic species are presented based on this hybrid and on recent results in grammitid phylogenetics.

Managing a wireless sensor network is not a trivial task. Due to its limitations, such as sensors equipped with low power batteries, it is essential to extend the lifetime of the network. This task becomes harder when dealing with heterogeneous wireless sensor networks, in which sensors have different physical characteristics, such as battery capacity and radio transmission range. This paper proposes a model to dynamically select a sensor allocation approach in order to choose a set of sensors to process an application request. This selection takes into account the application characteristics and the physical aspects of the sensors.

The number of urban vehicles has increased in the past years causing innumerous problems such as traffic jams, accidents and pollution. One of the main solutions for this problem is to improve the quality of public transportation by making it more reliable, secure and efficient. In this paper, it is proposed a system for monitoring urban vehicles based on ZigBee technology, called MUV-Bee. Such system uses wireless communication to integrate the main server to public transportation buses and bus stops. Its several services provided to society allow a better quality of public transportation which make them more attractive.

Pleroma setosociliatum (Cogn.) F.S. Mey. & F.B. Matos, from the states of Paraná and Santa Catarina, Brazil, has been indicated, still as a name in Tibouchina, as a synonym of T. dubia (Cham.) Cogn. on several floras and electronic databases. However, field observations and a more detailed analysis of herbarium specimens, including the types, led to the conclusion that these two species are distinct. They differ from each other not only in geographic distribuition, but also in growth habit, leaf size, indument, and dimensions of the connectives on antesepalous stamens. Tibouchina setosociliata is here transferred to Pleroma on the basis of morphology and results of a previously published molecular phylogeny.

QoS adaptation is an important process in inter-domain service management, since it can guarantee the correct service provisioning when unexpected events occur. However, in inter-domain environments, the human interference and the manual-based operations hamper the deployment of expeditious mechanisms to adapt the QoS of the services. This paper presents an approach based on SOA principles to perform QoS adaptation in these environments. This approach allows providers to determine the new QoS parameters, renegotiate these parameters with other providers along the provisioning path, update their contracts and enforce the changes in the equipment configuration in an automatic and on-demand fashion. The QoS adaptation process can be caused by technical (QoS violations, infrastructure malfunctions) or business (financial problems) issues. In addition, if a provider configuration in the provisioning path already supports the new requirements, this provider is not affected by the adaptation, thus decreasing the processing time.

Inter-domain QoS-aware service provisioning is still a complex task due to the Internet heterogeneity. It is necessary to overcome several obstacles in order to achieve a scenario where providers fully interact to satisfy all customer service requirements. Some of these obstacles are service class specification and service composition. This paper presents an integrated approach for service class specification and service composition that supports the provisioning of QoS-aware services in inter-domain environments. This approach makes use of QoS performance parameters, service-specific parameters and business parameters to compose services that fulfill customer requirements and comply with providers' business expectations.

In this paper we propose a new solution to increase the security of BGP/MPLS IP VPNs established across multiple domains. In general, layer 3 VPNs already present a number of security risks when used in single domain scenarios, since they are vulnerable to attacks originated inside the provider backbone. In order to overcome these risks, IPSec tunnels are recommended. In multi-domain scenarios, however, the safe establishment of such IPSec tunnels is much more difficult, due to need to set up proper Security Associations in an open environment. The solution we present in this paper not only solves this problem but also improves the dynamic composition of multi-domain VPNs, thus reducing the effort and time required to provide such VPNs.

The Mata Viva Reserve presents an area of about 5.5 hectares, which belongs to the Universidade Federal do Parana (25o 26’ S and 49o 14’ W). Its vegetation is mainly represented by disturbed forest, representing a remnant of the Araucaria forest inside the city of Curitiba. In this paper we present a general floristic survey and a structural analysis of the arboreal vegetation, providing information for management plans and further studies on the biological diversity of this area. One hundred and seventy four species of seed plants were found, being Asteraceae, Solanaceae, Myrtaceae, Euphorbiaceae and Leguminosae the richest families. For the structural analysis, 656 trees (60 spp.) were sampled, and the species with the highest Importance Values were Schinus terebinthifolius, Lithraea brasiliensis, Allophylus edulis, Casearia sylvestris and Symplocos uniflora. The vegetation of the Mata Viva Reserve presents a high plant diversity and a considerable wealth of specimens in a relatively small area. It is important to notice that exotic species represents about 25% of the individuals in the reserve, with a high influence on the native vegetation

Virtual private networks (VPNs) are a popular and cost-effective means to build wide-area corporate networks, since they provide bandwidth, privacy and security for a fraction of the cost of private networks. However, establishing VPNs across different domains (inter-domain VPNs) is still a cumbersome task, requiring human- based negotiation between involved carriers, manual configuration of network equipment and inefficient exploitation procedures during the whole VPN life cycle. For these reasons, inter-domain VPNs are usually contracted in a long-term basis and thus appropriate only for a limited set of usage scenarios. In this paper we propose a framework for efficient provisioning of inter-domain VPNs, comprising a business layer for inter-carrier negotiation and orchestration, policy-based mechanisms for intra-domain resource management, and RFC 4364-based mechanisms for configuration of VPNs. This framework will allow ISPs to provide much more elastic VPN services, able to support not only traditional VPNs (contracted for long periods, for interconnection of corporate networks) but also a new class of more granular, on-demand VPNs for support of shorter-term services such as videoconference sessions or internet banking transaction.

The low prices and the friendly usage of the mobile devices are contributing to increase the number of people who are using them for several tasks, as to pay a bill in an Internet banking, purchase a product, connect to a close printer and so on. Due to this, it is necessary develop applications which can cope with these new user habits. This paper proposes a context-aware negotiation model for mobile commerce between two participants, using mobile agents and taking into account the mobile device personalization. The model copes with the context-aware concepts through the use of created profiles. With these profiles it is possible to automate some tasks depending on the context, as for example the user identity.

This work proposes an automated negotiation model between two participants, for m-commerce, using mobile agents and considering the mobile device personalization through the use of profiles in the negotiation.
