Privacy Negotiation in Socio-Technical Systems  [PDF]
Murthy Rallapalli, Dinesh Verma
Technology and Investment (TI) , 2012, DOI: 10.4236/ti.2012.31003
Abstract: A socio-technical system (STS) is an approach to complex organizational work design that recognizes the interaction between people and technology in workplaces. The term also refers to the interaction between society’s complex infra-structures and human behavior. In this sense, society itself, and most of its substructures, are complex socio-technical systems. This paper addresses a class of socio-technical systems, represented by web services in a number of domains and attempts to understand the possibility of empowering the web users and consumers to have a say in the develop-ment of privacy agreements. This paper examines the likelihood of the web users and consumers leveraging such a capability, should it exist. This should improve the way privacy agreements are handled that benefits both the service providers and the web users.
Free Convection MHD Flow past a Vertical Plate with Constant Suction
Dinesh Verma,Monika Kalra
International Journal of Innovative Technology and Exploring Engineering , 2013,
Abstract: The special effects of fluctuating gravitational field on free convection MHD flow past a homogeneously moving infinite erect porous plate with constant suction velocity in a porous medium have been analyzed. A constant heat flux is prearranged on the plate. The gravitational field is implicit in the form . The governing equations are solved by perturbation method. Fluid velocity and fluid temperature shows remarkable alter with alteration in gravitational field. Small increase in gravity modulation parameter shows considerable increase in amplitude of skin friction and has insignificant decreasing effect on phase of skin friction.

An Improved Approach for Reduction of Defect Density Using Optimal Module Sizes
Dinesh Verma,Shishir Kumar
Advances in Software Engineering , 2014, DOI: 10.1155/2014/803530
Abstract: Nowadays, software developers are facing challenges in minimizing the number of defects during the software development. Using defect density parameter, developers can identify the possibilities of improvements in the product. Since the total number of defects depends on module size, so there is need to calculate the optimal size of the module to minimize the defect density. In this paper, an improved model has been formulated that indicates the relationship between defect density and variable size of modules. This relationship could be used for optimization of overall defect density using an effective distribution of modules sizes. Three available data sets related to concern aspect have been examined with the proposed model by taking the distinct values of variables and parameter by putting some constraint on parameters. Curve fitting method has been used to obtain the size of module with minimum defect density. Goodness of fit measures has been performed to validate the proposed model for data sets. The defect density can be optimized by effective distribution of size of modules. The larger modules can be broken into smaller modules and smaller modules can be merged to minimize the overall defect density. 1. Introduction The reliability of a software product is an important factor, being considered by the developer before the formal release of a product. Defect density (DD) is an important attribute that affects software reliability. Defect prediction is very important for estimation of defect density. There are many methods available that can be used to predict the number of defects in software during testing phases [1]. Estimation of this attribute is one of the approaches used to establish readiness for release. There are several methods that can be used to predict or estimate the value of this parameter. Six sigma methods are used by Fehlmann [2] for advanced prediction of defect density for software that has been developed and its development process is moving further for production. Mark [3] has presented a DevCOP method that has been used for estimation of defect density using verification and validation certificate technique. There are a few crucial factors that have an effect on the initial defect density. Analysis of these factors is important because it provides a quantitative method of identifying possible techniques for reducing the insertion rate of defects. Further, this analysis can be used to estimate initial defect density that may be used later while planning the required effort for testing. In present scenario many models are
Management of ocular perforations resulting from peribulbar anaesthesia
Puri Pankaj,Verma Dinesh,McKibbin Martin
Indian Journal of Ophthalmology , 1999,
Abstract: Purpose: To analyse the clinical presentation and outcome of treatment for globe perforation secondary to peribulbar anaesthesia. Methods: Eight patients (3 females and 5 males) aged 66-84 years were included in the study. Ocular perforations were suspected in 3 cases before or during surgery, in 4 cases diagnosis was established within one week and in one case at 3 weeks. Three patients underwent indirect argon laser photocoagulation to seal the retinal break, one patient had cryotherapy, 3 patients underwent a pars plana vitrectomy with fluid gas exchange and endolaser; and one patient refused any further treatment. Results: The final visual acuity after a mean follow up of 14 months was better than 6/9 in 2 patients, between 6/9-6/12 in 4 patients, and perception of light in 2 patients. Conclusion: If diagnosed early and treated adequately, a majority of patients with globe perforation during periocular anaesthetic could be saved
In Search of Systems “DNA"
John Boardman,Brian Sauser,Dinesh Verma
Journal of Computers , 2009, DOI: 10.4304/jcp.4.10.1043-1052
Abstract: General Systems Theory (GST) has been an attempt to put precision into the term system thereby making intelligent communication between its users more attractive, something that provides for migration of ideas and the possible resolution of issues by borrowing solutions from unfamiliar domains. We propose to build on GST and in particular, as von Bertalanffy once did, draw on the biological sciences, now hugely advanced beyond that ever imagined by von Bertalanffy and his peers, and use its findings, architectures and emergent behaviors, to argue for a biology of technology and enterprise systems. We do so by expanding on a system of “togetherness characteristics” and in particular explain how these can be applied to better understand familiar systems, e.g. the automobile, and how such systems form part of diverse wider communities (or containing systems). We seek a science and approach that we believe will provide richer insight into system failure, 'health' maintenance, repair, replication, growth, and mutation, all those features of the evolution of systems which constantly challenge us and which thus far we have only been able to explain via macro-level models and tools. We propose to go deeper into the structure of these systems and to discover the "DNA" (building blocks) of these systems. Thus establishing a foundation to understand their behavior using biological analogies which we believe will turn out to be more than metaphors. We assert that these systems have micro-structures which will explain their individual life cycle and their communal ecology.

Elastic Moduli of Carbon Nanohorns
Dinesh Kumar,Veena Verma,H. S. Bhatti,Keya Dharamvir
Journal of Nanomaterials , 2011, DOI: 10.1155/2011/127952
Abstract: Carbon nanotube is a special case of carbon nanohorns or carbon nanocones with zero apex angle. Research into carbon nanohorns started almost at the same time as the discovery of nanotubes in 1991. Most researchers focused on the investigation of nanotubes, and the exploration of nanohorns attracted little attention. To model the carbon nanohorns, we make use of a more reliable second-generation reactive empirical bond-order potential by Brenner and coworkers. We investigate the elastic moduli and conclude that these nanohorns are equally strong and require in-depth investigation. The values of Young's and Shear moduli decrease with apex angle.
First contact management of post-operative endophthalmitis. A retro-spective analysis
Verma Lalit,Patil Rajashekar,Talwar Dinesh,Tewari Hem
Indian Journal of Ophthalmology , 2004,
Abstract: Records of 37 consecutive patients of postoperative endophthalmitis referred to our centre from North India were retrospectively analysed to study the first contact management profile. Ten (27%) patients had received intravitreal antibiotics as a primary mode of treatment, and 27 (73%) had received only parenteral antibiotics. The outcome was worse in the latter group. This suggests that general ophthalmologists lack the capability to provide adequate treatment to patients with endopthalmitis in Northern India.

DINESH SINGH*, MAHINDER SINGH and V.S. VERMA
Indian Phytopathology , 2011,
Abstract: Prevalence and distribution of wheat foliar blight pathogens in Shivalik foothill region of Jammu and Kashmir (India) and effect of sowing dates on disease severity were analyzed for four rabi seasons from 2001-02 to 2004-05. Helminthosporium sativum, Alternaria triticina, H. spicifer and Pyrenophora triticirepentis were isolated with an average frequency of 66.87, 23.65, 3.97 and 3.50 per cent, respectively and highest frequency of isolation was 72 (Rajouri), 26.5 (Jourian, Doda and Bhaderwah), 5.5 (Akhnoor) and 4.5 (Kathua and Katra), respectively. Setosphaeria halodes and Helminthosporium bico/or were occasionally found associated. Early sowing (October, 25) was found to be significantly most effective in reducing the disease severity which was 3.66, 3.66, 3.66 and 2.33 per cent with variety PBW 175 and November, 14 sowing recorded the maximum grain yields of 21.67, 22.05, 21.70 and 22.90 qha·1 having disease severity of 16.66, 18.33, 21.66 and 18.33 per cent with the variety PBW 299 in the crop season 2001-02, 2002-03, 2003-04, 2004- 05, respectively. Meteorological parameters significantly influenced the grain yield and disease incidence. The maximum pooled grain yields of 22.08, 20.01, 21.37, 22.10, and 18.98 qha' were recorded on November ,14 sown crop where meteorological parameters were optimum for the whole crop season and minimum pooled disease severity of 11.66, 12.49, 3.32, 5.91 and 24.58 was recorded on October, 25 sown crop where environmental condition for the growth of crop was optimum according to its different stages but unfavorable for the pathogen during the susceptible s
