Targeting at a comprehensive Multiphysics evaluation for Al wire and ribbon bonding technologies for WBG power module, this paper investigates and compares the stray inductance, heat dissipation and fatigue life between these two bonding schemes in an XHP packaging designed in house. During calculation, it was tried to keep equivalent volume for the Al ribbon when substituting local Al wires for fair comparison. Results of stray inductance show extremely limit bonding-type dependence in ranges from 1 kHz to 10 MHz, and further expanding ribbon size to varied levels still presents negligible impact. The two bonding technologies do not prove their capability in sharing either static or transient thermal loads when the baseplate bottom is efficiently liquid cooled. Detailed study confirms that heat dissipates dominantly in vertical direction to the Cu baseplate rather than through Al bonds. Ultimately, the only noticeable benefit of Al ribbon in our multiscale analysis is its improved reliability during temperature cycling, with data supporting a 2.17× times longer lifetime of Al ribbon when comparing to its Al wire counterpart.

Determining the severity level of hypoxemia, the scarcity of saturated oxygen (SpO2) in the human body, is very important for the patients, a matter which has become even more significant during the outbreak of Covid-19 variants. Although the widespread usage of Pulse Oximeter has helped the doctors aware of the current level of SpO2 and thereby determine the hypoxemia severity of a particular patient, the high sensitivity of the device can lead to the desensitization of the care-givers, resulting in slower response to actual hypoxemia event. There has been research conducted for the detection of severity level using various parameters and bio-signals and feeding them in a machine learning algorithm. However, in this paper, we have proposed a new residual-squeeze-excitation-attention based convolutional network (Res-SE-ConvNet) using only Photoplethysmography (PPG) signal for the comfortability of the patient. Unlike the other methods, the proposed method has outperformed the standard state-of-art methods as the result shows 96.5% accuracy in determining 3 class severity problems with 0.79 Cohen Kappa score. This method has the potential to aid the patients in receiving the benefit of an automatic and faster clinical decision support system, thus handling the severity of hypoxemia.

Network automation has evolved into a solution that emphasizes efficiency in all areas. Furthermore, communication and computer networks rely on a platform that provides the necessary technological infrastructure for packet transfer through the Internet using routing protocols. Border Gateway Protocol (BGP) is a standardized gateway protocol that exchanges routing information across autonomous systems (AS) on the Internet. The traditional technique to configure BGP is inefficient compared to the network automation concept. Network automation helps to assist network administrators in automating and verifying the BGP configuration using scripting. This paper implemented network automation using Ansible to configure BGP routing and advanced configuration in the live network environment. This study is focused on automated scripting to configure IP Addresses to the interfaces, BGP routing protocol, configuration backup. Ansible ran the scripting on Network Automation Docker and pushed the configurations to the routers. The network automation controller communicated with other routers via SSH. The findings show that Ansible has successfully deployed the configuration to the routers with no errors. Ansible can help network administrators minimized human mistakes, reduce time-consuming and enable device visibility across the network environment. This study can help network administrators minimized human mistakes, reduce time-consuming and enable device visibility across the network environment. Implementing different types of authentication and hardening process can enhance the network security level for future

A power plant is a facility for the generation of bulk electric power. Power plants produce electric energy from another form of energy. In our country the crisis of electricity in national grid is a common problem where in industrial sector the electricity is required for 24 hours in a day. Due to failure of national grid non-public business house owners are exploitation their own power plants combining with national grid to fulfil the demand of electricity. The most common fuels used in Santahar power plant (50MW) are HFO and LFO. This article is describing about the power generation distribution and maintenance, Protection and controlling of that plant, different major components of power station such as diesel or HFO engine, compressor, fuel system, operation and control unit, cooling system and maintenance procedures of the plants.

Three-level (3L) inverters suffer from higher parasitic inductance due to the increased number of series-connected switches in a single current commutation loop (CCL) results in a larger size of CCL compared to their two-level (2L) counterparts. As such, semiconductors are subjected to higher voltage stress and severe ringing at the switching transient. While silicon carbide's (SiC) faster switching speed improves overall efficiency by reducing switching loss, the faster voltage, and current gradient (d v /d t and d i /d t ) generate electromagnetic interference (EMI) noise, requiring a larger and complicated filter stage design. To solve this problem, an optimized 3L T-type neutral point clamped power module has been proposed with a hybrid combination of the switch (SiC mosfet + Si IGBT) rated for 1200 V/160 A. Two direct bonded copper (DBC) substrates have been stacked to have a vertical power loop using laser-drilled vias, which provides low commutation loop inductance as low as 4.6 nH for the major CCLs including the wire bond. Other associated CCLs have also been identified and optimized. Additional DBC in the package will be acting as an EMI shield. The EMI noise has been compared to a traditional power module and a 21 dB reduction of common-mode noise has been observed.

Aim and Objective: To find out the role of increased sexual activity in expulsion of distal ureteral stone size 5 to 10 mm in married male. Material & Method: The study was conducted in FJMU/SGRH Lahore. 60 Married male in age range of 20-45 years were included in the study. Diabetic and hypertensive patients were excluded. The patients were divided randomly into 2 groups of 30 patients in each group. Patient in group A were advised to have sexual intercourse 3-4 times a week along with symptomatic treatment for 4 weeks. Patients in group B were advised not to have sexual activity or masturbation during the 4 weeks of study and given symptomatic treatment. alpha-blocker blocker were not used in either group. Informed consent was taken, ethical issues were taken into account. Telemedicine was utilized. Patients were instructed to pass the urine in a container, to record the stone expulsion day/week, number of pain attacks and number of analgesic injections required per week. Data regarding age, stone size, stone expulsion day/week and number of colicky attacks per week were recorded. Difference between two groups analyzed using chi-square test. P value less than 0.05 will be taken as significant. The patients whose symptoms worsened or who went into urosepsis were admitted on priority basis for ureteroscopic lithotripsy. Follow up done on weekly basis by history/examination, ultrasonography KUB, digital x-ray KUB and plain CT KUB. Results: Age range was 20-45 years in both groups. In group A stone size was 5-6.9 mm was in 14/30 patients (46.6%). 7-8.9 mm in 12/30 patients (40%) and 9-10 mm in 4/30 patients (13.3%). In group B stone size range 5-6.9 mm was in 13/30 patients (43.3%), 7-8.9 mm in 12/30 patients. (40%) in 9-10 mm in 5/30 patients (16.6%). In group A stone expulsion at the end of first two weeks was 76.6% and in 3 to 4th week it was 86.6%. in group B stone expulsion in first two weeks was 55% and 73.3% in 3rd to 4th week. In group A number of colicky attacks in first two weeks were 43.3% and in 3rd to 4th week were 23.3%. in group B number of colicky attacks in 1-2 weeks were 53.3 % and in 3 to 4 weeks were 30%. Conclusion: Married males, with distal ureteral stones (5-10mm), who practice sexual intercourse 3-4 times / week have increased stone expulsion and decreased frequency of ureteric colicks and the need for analgesia. Increased sexual activity has emerged as a new modality in MET, however further clinical trials are needed.
