This research work is part of a project to get an M.A. degree. Some of the linguistic sciences specialized in the search for meaning in the text, such as semantics, pragmatics, cognitive linguistics and etc. will be clarified. Besides, we shed light on the elements of semantic analysis with examples according to the basic scheme theory of reference, which indicates that the language is of a fictional nature. As it is a variety of similarity and symmetry relations between the form of the word and its meaning, whether it is phonetic or written or related to metaphor, metonymy or analogy, and it is not a random relationship. In all these genres, a very important role is played by imaginative comprehension, which subsequently acquires a traditional character and spreads due to the common collective understanding of the word among speakers of the speech community.

The process of splitting the image into many segments can be called as image segmentation. The main aim of this process is to recognize the object in an image. Let’s take an example a person wants to cross the road the first thing he’ll do is he’ll look at his right side first then left. If no vehicle is coming then the person will try to cross the road apart from that, this person will also check whether there is any electric poll or dog or is there any whole in the ground etc. The point is we’re doing object detection first then we’re crossing the road. Same thing we’ll train our machine to do but it can’t recognize directly the way humans do. We have to train the model first for that we’re doing image segmentation. This step is typically used to recognize the objects or other relevant information.

A modified mixed Gaussian plus impulse image denoising algorithm based on weighted encoding with image sparsity and nonlocal self-similarity priors regularization is proposed in this paper. The encoding weights and the priors imposed on the images are incorporated into a variational framework to treat more complex mixed noise distribution. Such noise is characterized by heavy tails caused by impulse noise which needs to be eliminated through proper weighting of encoding residual. The outliers caused by the impulse noise has a significant effect on the encoding weights. Hence a more accurate residual encoding error initialization plays the important role in overall denoising performance, especially at high impulse noise rates. In this paper, outliers free initialization image, and an easier to implement a parameter-free procedure for updating encoding weights have been proposed. Experimental results demonstrate the capability of the proposed strategy to recover images highly corrupted by mixed Gaussian plus impulse noise as compared with the state of art denoising algorithm. The achieved results motivate us to implement the proposed algorithm in practice.

Pigeons have accompanied humans since ancient time because they are used as a source of food, pets, hobby, and religious symbols. Pigeons have shown high prevalence rate of infection with gastrointestinal helminths and protozoan. This study was conducted to evaluate the prevalence of parasitic infections in the domestic pigeon (Columba livia domestica) from October, 2017 to April, 2018, purchased from bird market of Zakho City, Kurdistan region. The samples were taken from 50 adult pigeons (28 males and 22 females). The birds were transferred to Parasitology Laboratory, Faculty of Science, Zakho University. In the laboratory, each bird was sacrificed and immediately the feather and skin of under wings, chest and the rest of the body was examined for ectoparasites. The collected ectoparasites were preserved in 70% alcohol for further study. The sacrificed birds were dissected and their intestine and contained were examined for the presence of parasites. The results revealed a total rate of 76% of infection with ectoparasites, which included three species of lice, namely: Columbicola columbae (56%), Companulotes compar (36%) and Hohorstiella lata (10%). Regarding helminths, cestodes were the only helminths found in this study with a rate of 16% (8/50). Three species of cestodes were recorded, they included: Raillietina cesticillus(14%), Raillietina echinobothrida(4%) and Choanotaenia infundibulum (2%). Further studies are required to evaluate the effect of the recovered parasites on this host and their transmission to other poultry flocks and human.

A column is a structural member that bears an axial compressive load and is more likely to fail due to buckling than due to material strength. Some of these columns work at high temperature and this temperature effects the behavior of buckling. Then the designer must takes this factor into consideration. The present work involves the high-temperature buckling of 6061-T6 aluminum alloy rod(column) at different range of temperature (room temperature to 200°C). This work study the critical buckling load (Pcr) under the above temperature dynamically. The (Pcr) can be predicted by Euler theory. It has been observed that the Euler theory is not satisfy to applied under high temperature unless using temperature safety factor. The results show that elevated temperature weakens the structure and decreasing its mechanical and buckling properties. From the experimental results, empirical equations were derived to predict yield strength, ultimate tensile strength, modulus of elasticity, critical buckling load and temperature safety factor at high temperature.

The effect of three stir casting temperatures (ST) (900, 1000, and 1100 on magnetic and microstructure properties of AA5052 reinforced with 5wt% TiO2 nanoparticles has been investigated using the stir casting technique. It was found that the magnetic properties decrease with increasing stir casting temperature and the least magnetic saturation (Ms) and magnetic susceptibility (Xm) occurred for nanocomposite fabricated under stir casting temperature (1000 °C) also the maximum coercivity (Hc) and residual magnetization (Mr) occurred in this nanocomposite. The values of magnetic saturation (Ms), coercivity (Hc) and residual magnetization (Mr) obtained for nanocomposite under (1000 °C) are 2.714×10−6 (A/m), 4676.55530 (A/m) and 3.25032 ×10−8 (A/m), respectively. Scanning electron microscopy (SEM) is used to analyze the microstructure, and it is discovered that well-distributed nano particles lead to decrease grain size in the parent phase.

The INS system’s update rate is faster than that of the GNSS receiver. Additionally, GNSS receiver data may suffer from blocking for a few seconds for different reasons, affecting architecture integrations between GNSS and INS. This paper proposes a novel GNSS data prediction method using the k nearest neighbor (KNN) predictor algorithm to treat data synchronization between the INS sensors and GNSS receiver and overcome those GNSS receiver’s blocking, which may occur for a few seconds. The experimental work was conducted on a flying drone over a minor Hungarian (Mátyásföld, 47.4992 N, 19.1977 E) model airfield. The GNSS data are predicted by four different scenarios: the first is no blocking of data, and the other three have blocking periods of 1, 4, and 8 s, respectively. Ultra-tight architecture integration is used to perform the GNSS/INS integration to deal with the INS sensors’ inaccuracy and their divergence throughout the operation. The results show that using the GNSS/INS integration system yields better positioning data (in three axes (X, Y, and Z)) than using a stand-alone INS system or GNSS without a predictor.

This paper presents a high quality design of a 7th order Type-I Chebyshev low-pass filter (LPF) based on a stepped-impedance (SI) metamaterialized microstrip. The respective methodology involves embedding split ring resonators (SRRs) in addition to complementary split ring resonators (CSRRs) in filter design. The introduced metamaterialized filter manifestd better characteristics than in the conventional filter design and in some other availablefilter designs achieving lower insertion loss and appreciable size reduction. In this metamaterialized filter, miniaturization has been attained through implanting rectangular SRRs on top of the microstrip line besides etching squared CSRRs in its ground plane forming a defected ground structure (DGS). The design shows voltage standing wave ratios (VSWRs) of less than 1.05 in the pass-band interval yielding flattest pass-band with clear impedance matching. The shown group delay (GD) pattern is almost constant of around 0.5ns. Roger substrate material (RO3210) has been utilized with dielectric constant 10.2, substrate thickness 1.27mm, and thickness of microstrip conductor 0.035mm. Simulation outcomes have been obtained using the Ansoft High Frequency Structure Simulator (HFSS) package that is based on finite element method (FEM). The filter is applicable in most microwave (MW) and RF systems.

O presente trabalho descreve os sinais clínicos, as lesões macroscópicas e os aspectos histológicos observados em 25cordeiros acometidos em um surto de artrogripose congênita com hidrocéfalo ou hidrocefalia registrado no Iraque, governadoria Al-Muthama após a ocorrência de nascimentos prematuros e deformidades músculo-esqueléticas no período compreendido entre outubro de 2017 e maio de 2018. A hipoplasia músculo-esquelética foi observada nos membros dos cordeiros afetados, acompanhada de severa artrogripose e malformações cerebrais, grosseiras visíveis, além de mumifcações fetais, nascimentos prematuros e morte de cordeiros. Os principais aspectos histopatológicos nas fbras musculares foram lesões degenerativas e ausências da estriação cruzada acompanhada de leve infltração de neutróflos e células mononucleares dos cordeiros severamente afetados. As meninges dos cordeiros afetados apresentaram fusão de membranas com áreas focais de espessamento fbroso e debris necróticos. O vírus Akabane, um membro do gênero Orthobunyavirus, da família Bunyaviridae, causa anormalidades congênitas e artrogripose com hidrocéfalo e hidrocefalia em ruminantes e poderá vir a ser a causa do presente surto. Os autores recomendam a realização de novos estudos com investigações epidemiológicas e isolamento do agente causal. Contudo, outras causas de hidrocéfalo ou malformações cerebrais como as determinadas pelo vírus Schmallenberg, vírus da língua azul e vírus da doença de border, bem como de plantas teratogênicas que determinam a artrogripose, também deverão ser investigadas. As autoridades sanitárias deverão tomar medidas de prevenção e controle para bloquear a replicação do vírus em artrópodes vetores. Akabane virus, a member of the Orthobunyavirus genus in the family Bunyaviridae, causes congenital abnormalities and arthrogryposis with hydrocephalus or hydroencephaly in ruminants. Tis study intends to describe the clinical signs, gross and histopathological features seen in 25 afected lambs in an outbreak of congenital arthrogryposis with hydrocephalus or hydranencephaly in Al-Muthanna governorate, Iraq afer a large number of stillbirths and musculoskeletal deformities from October 2017 to May 2018. Skeletal muscle hypoplasia was seen in the limbs of the afected lambs accompanied with severe arthrogryposis and gross visible brain malformations. In addition, fetal mummifcations, stillbirths, and dead lambs were also seen. Te most histopathological features in muscle fbers were degenerative lesions and absences of cross-striation accompanied with mild infltration of neutrophils and mononuclear cells in severely afected lambs. Te meninges of afected lambs revealed fused membranes with focal areas of fbrous thickenings and necrotic debris. In conclusion, according to clinical signs, gross and histopathological investigations, Akabane virus, a member of the Orthobunyavirus genus in the family Bunyaviridae, causes congenital abnormalities and arthrogryposis with hydrocephalus or hydroencephaly in ruminants and could be the cause of this outbreak, although future studies must be performed to confrm the etiology of this outbreak. Moreover, other causes of hydrocephalus or cerebellar malformation, such as Schmallenberg virus, bluetongue virus and border disease virus and teratogenic plants that lead to arthrogryposis, have to be investigated. Also, the authorities should take prevention and control measurements to stop the replication of arthropod vectors.

Radio-frequency identification (RFID) is an important wireless technology which utilizes radio frequencies (RFs) for exchanging data between two or more points (tags and readers), that represent an automatic identification (Auto-ID) system. This paper introduces an omnidirectional microstrip antenna operates at 2.45 GHz used for a radio-frequency identification (RFID) technology. The length of the proposed antenna is 36.5 mm and the width is 27 mm. The substrate material which has been used as a base of antenna is FR4 that has dielectric constant value of 4.3 and dielectric thickness value of 1.6 mm. Regarding the resonance frequency, return loss of the proposed antenna design is -34.8 dB. A promising directivity outcome of 2.8 dB has been achieved with omnidirectional radiation pattern as well as an acceptable efficiency of 66%. The proposed antenna design accomplishes a wideband frequency of 1.21 GHz in the frequency range of (2.14 3.35) GHz. The computer simulation technology (CST) microwave studio software has been used for implementing the proposed antenna design. The antenna design fabricatation and its characteristics have been measured using vector network analyzer (type MS4642A).

This paper introduces several miniaturized symmetrical designs of high selectivity metamaterialized low-pass filters (LPFs) based on a stepped-impedance (SI) 3rd order Type-I Chebyshev LPF prototype. The pass-band interval of the prototype design manifests a nearly constant group delay (GD) ranging between 0.4–0.45 ns with lower level of ripples. It further exhibits voltage standing wave ratios (VSWRs) starting at value 1 and keeping on a reasonable level of impedance matching. To ensure for considerable metamaterialized LPFs designs, the methodology behind this work has resorted to exploit: split ring resonators (SRRs), complementary split ring resonators (CSRRs), besides open stubs (OSs). Qualities such as sharp cutoff, high selectivity, substantial size reduction, and low insertion loss, have all been achieved. The designs were applied on the Roger substrate material (RO3210) with dielectric constant of 10.2, substrate thickness of 1.27 mm, thickness of microstrip conductor of 0.035 mm, then simulated using the package Ansoft High Frequency Structure Simulator (HFSS). The applications field of these filters involves most microwave (MW) communication systems in diverse civil and military horizons.

Image compression solutions are a pivotal field that gain over a remarkable research interest and called upon to extend widely with respect to the increasing of its applications. The considerable challenge of this solution is related to the storage and bandwidth requirements. A highly compression rate with a high image resolution is considered to be the key factors for implementing a robust image compression technique. In this paper, the proposed method is deemed to be simple and effective due to using different levels of compression process which is starting from dividing the image into sub-images and using high level discrete wavelet transform (DWT). In addition, the Huffman code with non-uniform Quantizer has been used to minimize the compression data rate with high quality reconstructed image. The promising simulation results of the proposed method achieved the most two significant criteria which are denoted by high image quality and a high image compressed ratio. For instance, the proposed strategy simulation results of Lena image achieved PSNR equals to 42.4094 dB with a compression ratio (CR) equals to 47.5435. Moreover, the simulation results of Flower image accomplished PSNR equals to 42.8348 dB with a compression ratio equals to 55.3389 under the same simulation conditions.

When it comes to drawing 3D shapes, we do not get any easier than the Google Sketch Up program. The most important part of 3D drawing, especially in the field of architecture, is the ease of using the program, the ability to turn the idea into virtual reality, the Google sketch program Up, provides a user-friendly service that is not required for a powerful computer, and we all know that AutoCAD is one of the most powerful 3D drawing programs (if not the most powerful) but the difficulty of using it and the time it takes to learn has led most engineers to resort to the easiest program. indispensable but Google sketch programs gave up solutions faster and many choices in final directing. The study examined the problem of the use of the AutoCAD program and the suffering of the drawing teachers in understanding and using it. In contrast, it showed the advantages of the program, and compared it to the AutoCAD program, and presented a questionnaire by the researcher on a sample of the teachers of the engineering drawing in the degrading schools. program AutoCAD, and therefore, this program does not result in the expected purpose of it, so it became necessary to find an alternative at least to use it as a display of sculptures by engineering drawing teacher, and this alternative is a program Cockle Google sketch up.

This paper presents compact dual-band band-pass filters (BPFs) using microstrip transmission lines (TLs) loaded with metallic via holes (MVHs). The primary goals of the proposed design are to get size reduction and dual-band frequency response. An end-coupled line dual-band BPF with better size reduction has been obtained using MVHs as a single negative (SNG) metamaterial (MTM) component to achieve negative relative permittivity (ɛ r ). This component is adequate for designing dual-band BPFs to operate at 4.1 GHz and 6 GHz resonant frequencies. To the best knowledge of the authors of this work, “Dual-” band BPF based on MVH has not been experienced yet by any other work in the literature. The filters structure length is as small as one third of wavelength. The filters have been designed with a fractional bandwidth (δ) that exceeds 10% at the resonant frequencies. Numerical observations of the microstrip TL and end-coupled BPFs designs have all been discussed. Simulations were done by HFSS software and implemented on the substrate Roger RO3210 with dielectric constant of 10.8 and dielectric substrate height of 1.27 mm. These filters are convenient for most common microwave applications.
