Maximum Likelihood Decoder for Index Coded PSK Modulation for Priority Ordered Receivers

Index coded PSK modulation over an AWGN broadcast channel, for a given index coding problem (ICP) is studied. For a chosen index code and an arbitrary mapping (of broadcast vectors to PSK signal points), we have derived a decision rule for the maximum likelihood (ML) decoder. The message error performance of a receiver at high SNR is characterized by a parameter called PSK Index Coding Gain (PSK-ICG). The PSK-ICG of a receiver is determined by a metric called minimum inter-set distance. For a given ICP with an order of priority among the receivers, and a chosen $2^N$-PSK constellation we propose an algorithm to find (index code, mapping) pairs, each of which gives the best performance in terms of PSK-ICG of the receivers. No other pair of index code (of length $N$ with $2^N$ broadcast vectors) and mapping can give a better PSK-ICG for the highest priority receiver. Also, given that the highest priority receiver achieves its best performance, the next highest priority receiver achieves its maximum gain possible and so on in the specified order or priority.Comment: 9 pages, 6 figures and 2 table

An unusual case of metallic foreign body in the left knee: a rare case report

Foreign bodies in the knee joint are uncommon, particulary those not related to surgical procedures. We present a rare case of an intraosseous metallic foreign body penetrating the lateral femoral condyle at left knee causing pain, which was removed with complete resolution of the symptoms due to walking – running injury in a child

A COMPARATIVE CLINICAL STUDY ON APPLICATION OF YASHADA BHASMA LEPA AND JATYADI GHRITA IN THE MANAGEMENT OF DUSHTA VRANA W.S.R. DIABETIC ULCER

Introduction: Wounds and their management are fundamental to the practice of surgery. In surgery of trauma, wound is frequently a primary pathology. In elective surgery, it is through the wound that access is obtained to deal with the underlying pathology. In both situations surgeon’s task is to minimize the adverse effects of wound, remove or repair damaged structures and harness the process of wound healing to restore function.Objectives: The study is aimed to know the comparative efficacy of Yashada Bhasma Lepa and Jatyadi Ghrita in the management of Dushta Vrana.Method: Clinically diagnosed 30 patients of Dushta Vrana were randomly divided into two groups, each group consisting of 15 Patients. First (A group) is treated by Yashada Bhasma Lepa and second (B group) is treated by Jatyadi Ghrita for 21 days.Result: On the basis of assessment criteria and on the overall result of treatment the patients of Yashada Bhasma Lepa group showed better relief when compared to Jatyadi Ghrita.Interpretation: Yashada Bhasma Lepa having the properties of Tikta, Kashaya, Katu, Rasa predominance thus had action of Kapha Pitta Shamana, Netra Roga, Pandu, Bahumootra Roga, Kasa, Swasa, Rajayakshma, Ratrisweda, Vranasrava Avarodaka,Prameha, Sankochakara.etc. Thus this help for Shodhanaand Ropana.Conclusion: Yashada Bhasma Lepa has provided better relief in maximum signs and symptoms of the patients of Dushta Vrana, in comparison to Jatyadi Ghrita. Its overall effects were also better in comparison to Yashada Bhasma Lepawith Jatyadi Ghrita and dressing reduces the infection

Automated Design of Steel Trusses

Designing an automated procedure for the optimal design of any structural system poses special challenges. Converting this methodology into a practical tool is even more challenging. In this research, a point-and-click software system is developed for the optimal design of roof truss systems. The starting point is a roof template containing minimal user input - outline of the truss, truss spacing, load information, and cost figures. A ground structure is constructed as the starting point of the design iterations. The Genetic Algorithm (GA) is used as the optimization tool to drive the design changes. Using the database of available sections, the member cross-sections are selected for the top and bottom chords, and the webs. In addition, the number and layout of the web members is also determined. The final design is obtained so that the truss has the lowest cost and also satisfies AISI-LRFD design specifications. Numerical experience using the developed methodology and the software system on an Intel-based PC running Microsoft Windows OS shows that optimal designs can be obtained in a few minutes

Gonococcal osteomyelitis in a pediatric patient with disseminated gonococcal infection: Implications for antimicrobial management

© 2020 The Authors We report a case of a female teenager with gonococcal septic arthritis of the right shoulder that also caused osteomyelitis of the humeral head. Infection with Neisseria gonorrhoeae is a frequently diagnosed sexually transmitted infection in the sexually active teenage population and disseminated gonococcal infection (DGI) is the most common systemic manifestation of acute gonorrhea. DGI commonly involves acute arthritis, tenosynovitis and dermatitis with less common complications of endocarditis, hepatitis and meningitis. In contrast, osteomyelitis has only rarely been reported as a result of gonococcal infection. Clinicians need to be aware of this unusual manifestation of DGI as a prolonged duration of antimicrobial treatment may be needed to assure complete resolution of this infection

A Cost Based Approach to Design of Residential Steel Roof Systems

A comprehensive system for the design of residential steel roof truss systems is presented. The research involved three distinct stages. In the first stage, components of the truss systems were tested in order to determine their member properties subjected to axial force and bending moments. Finite element simulations of these tests were carried out to further verify the, calculations obtained using the AISI-LRFD code guidelines. The AlSI-LRFD code based design curves were used for the actual design, while the laboratory experiments and the finite element results provided additional checks and verification of the AlSI values. The second stage of the research involved the development of an integrated design system that would automatically design a roof truss given minimal input and using the design curves as the performance constraints. A design optimization scheme based on the genetic algorithm was adopted to handle sizing, shape and topology variables in the design problem. A software system was developed to design the lowest cost truss given the input parameters. The third stage of the research involved full-scale testing of typical, residential steel roofs designed using the developed software system. Roof trusses were loaded to failure. The full scale testing procedure established the factor of safety while validating the analysis and design procedures. Evaluation of the test results indicates that the present design system provides enough reserve strength for the structure to perform as predicted
