Issues in Analysis & Design of IDMA & its Application
PAURUSH BHULANIA,GAGAN MINOCHA,RICHA SHARMA
International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering , 2013,
Abstract: Interleave Division Multiple Access (IDMA) is one of the competitors for next generation wireless systems .IDMA not only inherits all the advantages of CDMA but also has the capability to overcome its deficiencies.This paper outlines a survey on interleave-division multiple-access (IDMA) technique which exploits the interleaving as only means of user separation instead of by different signatures as in a conventional code-division multiple-access (CDMA) scheme. IDMA scheme can achieve near single user performance in situations with very large numbers of users while maintaining very low receiver complexity. This technique inherits many advantages from CDMA, such as diversity against fading and mitigation of the worst-case user interference problem. The parallel and simultaneous execution of repetitive functions can be used to overcome the significant time delays involved in previous simulations of IDMA system. This paper presents an overview of IDMA and discusses the main features and areas of application as the future air interface access schemes for IMT-2000/UMTS.
Generating domain specific sentiment lexicons using the Web Directory
Akshay Minocha,Navjyoti Singh
Advanced Computing : an International Journal , 2012,
Abstract: based. There has been a demand for the construction of generated and labeled sentiment lexicon. Fordata on the social web (E.g., tweets), methods which make use of the synonymy relation don't work well,as we completely ignore the significance of terms belonging to specific domains. Here we propose togenerate a sentiment lexicon for any domain specified, using a twofold method. First we build sentimentscores using the micro-blogging data, and then we use these scores on the ontological structure providedby Open Directory Project [1], to build a custom sentiment lexicon for analyzing domain specific microbloggingdata.
An empirically grounded framework to guide blogging for digital scholarship
Tania Heap,Shailey Minocha
Research in Learning Technology , 2012, DOI: 10.3402/rlt.v20i0.19195
Abstract: This research project investigated how openness and sharing of knowledge are manifested through scholarly blogging. We aimed to identify the academics’ and researchers’ motivations for starting a blog; the contribution of blogging to their personal and professional development; and any challenges. Twenty-six participants were recruited. A pre-interview questionnaire was first emailed to the participants to collect background information. An initial unstructured interview was conducted by email, followed by a synchronous semi-structured interview. Textual and visual extracts of blog content were also collected. The datasets were analysed using different techniques. The findings revealed varied reasons for blogging. Some academics/researchers began a blog for its accessibility to self and others. Blogging aided the academics’ and researchers’ personal and professional development in several ways. Bloggers can quickly reach a wider audience compared to other forms of academic publishing. Among the challenges, there were concerns over validity of online content. Based on previous scholarship models and on our findings, we have derived an empirically grounded framework of blog use in academia and research. The framework describes how characteristics of digital scholarship such as openness and sharing are manifested through blogging. The framework can be used to guide academics and researchers who are interested in taking up blogging as a scholarly practice.
Laying the groundwork for socialisation and knowledge construction within 3D virtual worlds
Shailey Minocha,Dave Roberts
Research in Learning Technology , 2008, DOI: 10.3402/rlt.v16i3.10897
Abstract: The paper reports the theoretical underpinnings for the pedagogical role and rationale for adopting 3D virtual worlds for socialisation and knowledge creation in distance education. Socialisation or ‘knowing one another' in remote distributed environments can be achieved through synchronous technologies such as instant messaging, audio and video-conferencing. However, a 3D virtual world can provide an immersive experience where there is a visual presence and virtual proximity of the group members in terms of their 3D selves (avatars). We discuss the affordances of a 3D virtual world and its role in providing a platform for pedagogical design that engenders socialisation, synchronous communication and collaboration. We propose the use of a knowledge construction model as a framework for guiding the design of collaborative activities in a 3D virtual world for blended learning environments. We believe that this framework will also be useful for integrating 2D environments such as blogs, wikis and forums with a 3D learning environment. We consider the implications of this in the context of blended learning in distance education. This paper would be of interest to course designers, researchers, teachers, staff developers and policy-makers who are involved in integrating 3D virtual worlds within the curriculum of their programmes and institutions.
Lupus Nephritis in a Patient with Sickle Cell Disease
Vinay Minocha,Fauzia Rana
Case Reports in Hematology , 2013, DOI: 10.1155/2013/907950
Abstract: Introduction. The diagnosis of systemic lupus erythematosus (SLE) in patients with sickle cell disease (SCD) can be difficult to establish because the musculoskeletal, central nervous system, and renal manifestations are similar in both diseases. In the presented case, we highlight the diagnostic challenge that can evolve in patients with a concurrence of both diseases and we establish the importance of early recognition and treatment of lupus nephritis in patients with SCD. Case Presentation. We present a case of a 31-year-old African American female with sickle-C disease (hemoglobin SC) who was admitted to our hospital with complaints of periumbilical abdominal pain associated with intractable nausea and vomiting, abdominal distension, and worsening lower extremity edema. Urine studies revealed nephrotic range proteinuria and the immunological investigations were consistent with lupus. A renal biopsy revealed focal proliferative lupus nephritis. Conclusion. It is important to consider the presence of a coexisting autoimmune disease in a patient with sickle hemoglobinopathy who displays an atypical and multisystem presentation that is unresponsive to conventional therapies. When a significant kidney disease is present, a renal biopsy is critical in identifying the etiology of a renal abnormality in the setting of coexisting SLE and SCD. 1. Background Systemic lupus erythematosus (SLE), or lupus, is a chronic, progressive, autoimmune disorder that affects multiple organ systems, with a broad range of clinical and laboratory manifestations [1]. Sickle cell disease (SCD) encompasses a group of autosomal-recessive genetic disorders characterized by the production of abnormal hemoglobin S (HbS). The protean clinical features of SCD result from chronic variable intravascular hemolysis and microvascular ischemia, leading to damage in multiple organs [2]. The diagnosis of SLE in patients with an underlying chronic hemoglobinopathy can be difficult to establish because the musculoskeletal, central nervous system, and renal manifestations are similar in both diseases. In the presented case, we highlight the diagnostic challenge that can evolve in patients with a concurrence of both diseases and we establish the importance of early recognition and treatment of lupus nephritis in patients with SCD. 2. Case Presentation A 31-year-old African American female with sickle-C disease (hemoglobin SC) was admitted to our hospital with complaints of periumbilical abdominal pain associated with intractable nausea and vomiting, abdominal distension, and worsening lower
Child Health Status of Nepal: Social Exclusion Perspective
Gagan Gurung
Journal of Nepal Paediatric Society , 2009, DOI: 10.3126/jnps.v29i2.2044
Abstract: Introduction: Nepal has achieved a spectacular success in child health over the last decades but the achievement is not uniform across different social groups. Therefore, there is urgent need to identify the groups who are excluded from access of child health services which would give us population at risk to prioritize and utilize the scarce resources available in health sector more effectively and efficiently. Methods: The study was descriptive type and was based on review of secondary data of different studies done in past. The study used World Bank framework of dimension of exclusion to analyze social exclusion in child health in Nepal. The health differentials in child health across different social groups were analyzed using simple descriptive analysis like percentage and ratios. The trends of the child health disparities over the ten years were done comparing the data of NFHS1996 and NDHS 2006. Results: The study showed there were disparities in child health status by ethnicity, location, wealth status. In most of the cases, the trends of disparities are increasing for mortality indicators and malnutrition status. Interestingly, the gaps in accessibility indicators of child health services are becoming narrowed down. Conclusion: This study showed the discrepancies in child health status in different social groups. The inequality in childhood mortality and malnutrition are increasing over the period for different groups where as it is decreasing for accessibility indicators of childhood health services. Key words: Child health status, inequality, social exclusion, social groups. ? doi: 10.3126/jnps.v29i2.2044 J. Nepal Paediatr. Soc. Vol 29, No. 2, pp.79-84
Instant Replay: Investigating statistical Analysis in Sports

Computer Science , 2011,
Abstract: Technology has had an unquestionable impact on the way people watch sports. Along with this technological evolution has come a higher standard to ensure a good viewing experience for the casual sports fan. It can be argued that the pervasion of statistical analysis in sports serves to satiate the fan's desire for detailed sports statistics. The goal of statistical analysis in sports is a simple one: to eliminate subjective analysis. In this paper, we review previous work that attempts to analyze various aspects in sports by using ideas from Markov Chains, Bayesian Inference and Markov Chain Monte Carlo (MCMC) methods. The unifying goal of these works is to achieve an accurate representation of the player's ability, the sport, or the environmental effects on the player's performance. With the prevalence of cheap computation, it is possible that using techniques in Artificial Intelligence could improve the result of statistical analysis in sport. This is best illustrated when evaluating football using Neuro Dynamic Programming, a Control Theory paradigm heavily based on theory in Stochastic processes. The results from this method suggest that statistical analysis in sports may benefit from using ideas from the area of Control Theory or Machine Learning

Indian Journal of Dermatology, Venereology and Leprology , 2001,
Abstract: Parthenium dermatitis is one of the most intractable problems in dermatology, the management of which poses a therapeutic challenge. The mainstay of treatment has been systemic corticosteroids for prolonged periods which may result in various side-effects.ln the present study, 30 patients of parthenium dermatitis were treated with oral azathioprine in a dose of 1-3 mg/kg/day. Assessment was done at monthly intervals using a clinical score. Azathioprine emerged as an effective and safe corticosteroid sparing agent in the treatment of parthenium dermatitis, provided the patients are carefully monitored for the side effects.
