TL;DR: Performance analysis show that the proposed scheme for gray scale medical images based on the features of genetic algorithms has good statistical character, key sensitivity and can resist brute-force attack, differential attack, plaintext attack and entropy attack efficiently.
Abstract: The security of digital medical images has attracted much attention recently, especially when these images are sent through the communication networks. An image encryption technique tries to convert an image to another image that is hard to understand. In this communication, we propose an encryption method for gray scale medical images based on the features of genetic algorithms. Performance analysis show that the proposed scheme has good statistical character, key sensitivity and can resist brute-force attack, differential attack, plaintext attack and entropy attack efficiently.

TL;DR: The two faces available on the plant leaves are utilized, instead of one, for classification of plants on the basis of digital leafimages and the effects on classification accuracy values for dorsal and ventral sides of leaf images are analyzed.
Abstract: As the digital images produce a lot of information about the pixels, there is a need to find alternative methods to reduce the image feature dataset for faster and automatic classification of plants through digital leaf images. In the present work, the leaf image texture features have been extracted through Gabor based techniques and then subjecting them to PSO-CFS based search method for identifying the best set of features from the complete feature set and then classifying them using four classification algorithms like KNN, J48, CART and RF. Another objective of this work is to utilize the two faces available on the plant leaves (Dorsal and Ventral), instead of one (i.e. Dorsal) for classification of plants on the basis of digital leafimages and to analyse the effects on classification accuracy values for dorsal and ventral sides of leaf images.

TL;DR: In this paper, the need for replacement of traditional Performance Appraisal System (PAS) in public sector enterprises by using a case study approach selecting a public sector company, the Rajasthan State Mines and Minerals Limited.
Abstract: Performance appraisal is considered as a management tool which is often used for motivating and effective utilization of human resources. This tool is used for determining compensation, incentives, promotion, tenure, transfers, layoffs and development of potential employees in an organization. The basic objective of this study is to analyze the need for replacement of traditional Performance Appraisal System (PAS) in public sector enterprises by using a case study approach selecting a public sector company, the Rajasthan State Mines and Minerals Limited. The study highlights that employees perceive the PAS measures to be objective, accurate and unbiased, and the PAS system to be transparent, performance-based and linked to employee growth opportunities. Also, significant differences have been found in the perception of workers and managers on the given constructs of modified PAS.

TL;DR: In this paper, the authors used SPSS-19 software to identify whether on the basis of the perception and adoption it can be converted into the financial disclosure, since disclosures on human assets act as an evidence for wealth creation, it is proposes that companies should take the maximum benefits by adopting HRA.
Abstract: Human Resources are the most important assets of an organization, but due to absence of legal regulation in relation to Accounting of HR, their financial values were not disclosed in most of the company’s annual report. The main objective of this study is to analysis Indian companies and their HR practices. The perception of accounts managers and accountants working in Indian companies were taken to identify challenges faced to predict the organization’s performance. The data were collected from 100 accountants and managers from 15 Indian companies on the basis of benefits, measurement model and perception. The multiple regression method was used with SPSS-19 software to identify that whether on the basis of the perception and adoption it can be converted into the financial disclosure. Since disclosures on human assets act as an evidence for wealth creation, it is proposes that companies should take the maximum benefits by adopting HRA.

TL;DR: In this paper, the authors mainly focus on the global dynamical behaviour of some ubiquitous nonlinear oscillators under the presence of nonlinear dissipation and obtain the threshold condition for the occurrence of chaos analytically as well as numerically for all the cases.
Abstract: In this paper, we mainly focus our attention on the global dynamical behaviour of some ubiquitous nonlinear oscillators under the presence of nonlinear dissipation. We particularly consider the parametrically driven Duffing oscillator and externally driven Helmholtz–Duffing oscillators with nonlinear dissipation term proportional to the power of velocity $$(v\left| v \right| ^{p-1})$$ . We obtain the threshold condition for the occurrence of chaos analytically as well as numerically for all the cases $$p=$$ 1, 2, 3 and 4. We also identify the regions of 2D parameter space (consisting of external forcing amplitude and damping coefficient) corresponding to various asymptotic dynamics and analyse the effect of nonlinear damping on the overall dynamical behaviour of these nonlinear oscillators.

TL;DR: The purified trypsin inhibitor protein from M. dioica seeds were found to posses serine protease inhibitor protein, which can be well explored for its use in the agriculture industry for pest management as well as the therapeutic applications.
Abstract: Objective: To purify the trypsin inhibitor protein from the seeds of Momordica dioica and characterize the protein for its stability and effect on trypsin activity. Methods: The total protein was extracted from the seeds of M. dioica, and the purification of the protein was performed by ion exchange chromatography and ultrafiltration technique. The antitrypsin activity assay of the purified inhibitor protein was carried out using N-benzoylDL-arginine-p-nitroanilide (BAPNA) as the chromogenic substrate at various pH and temperature ranges to determine the stability of the protein. The inhibitory effect of purified protein on trypsin activity was characterized by enzyme kinetic study. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis was performed under the non-reducing condition to determine the presence of inhibitor protein in various fractions of elutes and its molecular mass. Results: The purified protein from M. dioica seeds showed almost 96.17±0.034% trypsin activity inhibition and 0.96±0.00 U trypsin inhibitory activity (TIA) at 30°C and pH 8. This trypsin inhibitory protein from M. dioica (MdTi) was found to be stable over a temperature range of 30-100°C and the pH range of 3-10 retaining the antitrypsin activity. The molecular mass of MdTi was found to be 12 kDa. From the enzyme kinetics, it was found that Km value remains unaffected with decrease in the Vmax of trypsin in presence of inhibitor. Conclusion: M. dioica seeds were found to posses serine protease inhibitor protein. The protein was purified and characterized as thermostable as well as pH tolerant trypsin inhibitor with high TIA. It can be well explored for its use in the agriculture industry for pest management as well as the therapeutic applications. Keywords: Serine proteases, Trypsin inhibitor, Momordica dioica, Trypsin inhibitory protein from Momordica dioica, Non-competitive inhibition.

TL;DR: In this paper, Ren et al. calculated FDCS in the second Born approximation and treated the postcollision interaction to describe the collision dynamics of electron-impact double ionization of helium atoms.
Abstract: Fully differential cross sectional (FDCS) results are reported for the electron-impact double ionization of helium atoms at 5 and 27 eV excess energy. The present attempt to calculate the FDCS in the second Born approximation and treating the postcollision interaction is helpful to analyze the measurements of Ren et al (2008 Phys. Rev. Lett. 101 093201) and Durr et al (2007 Phys. Rev. Lett. 98 193201). The second-order processes and postcollision interaction have been found to be significant in describing the trends of the FDCS. More theoretical effort is required to describe the collision dynamics of electron-impact double ionization of helium atoms at near threshold.

TL;DR: This work proposes a mechanism that relies on unicast unicast broadcast (UUB) variant of fixed sequencers atomic broadcast in order to build moving sequencer atomic broadcast.
Abstract: This article investigates a new mechanism to design moving sequencer based atomic broadcast in distributed systems. There are two very crucial observations have been drawn from [1], (i) fixed sequencer based atomic broadcast mechanisms are build upon either unicast broadcast (UB) or broadcast broadcast (BB) or unicast unicast broadcast (UUB) variant and (ii) moving sequencer based atomic broadcast can also be designed with the help of any of three variants (UB, BB or UUB). The various mechanisms given for moving sequencer based atomic broadcast like RMP [2], DTP [3] and Pin Wheel [4] are based on broadcast broadcast (BB) variant of fixed sequencer atomic broadcast. While mechanism proposed in [5] is based on unicast broadcast (UB) variant of fixed sequencer atomic broadcast. This work proposes a mechanism that relies on unicast unicast broadcast (UUB) variant of fixed sequencer atomic broadcast in order to build moving sequencer atomic broadcast. This work does not give any comparison with other mechanisms but it presents a new way to design moving sequencer atomic broadcast. B formal method [6] has been used to design different models for atomic broadcast and ProB [7] model animator and checker tool has been used to verify it.

TL;DR: A new energy Adaptive routing mechanism based on AODV is proposed in this paper which selects the path based on node energy, which enforces a fair energy consumption rule on all the nodes of the network between source and destination.
Abstract: Ad- hoc network is defined as the network in which the users communicate with each other by forming a network on-fly without any centralized node or base station Here each node act as a host as well as a router and allow packet forwarding to neighbours Ad hoc networks are highly dynamic in nature They have highly deployable and self-configurable topologies Due to self- organizing, self-configuring capability MANET is used in different areas like emergency search and rescue, military, etc Various routing protocols are defined for these Mobile Ad-hoc networks One of main problem in Ad hoc network is energy issue in mobile nodes As the Ad-hoc network node operates on battery power the routing algorithms must take account the node battery status while selecting the routing path between source and destination The reason of packet drop in MANETs is link break which could be a result of mobility or node failure (due to battery exhaust or some hardware failure) Each drop packet is an energy wastage used in transmission and reception of the dropped packet The existing routing protocols for MANETs do not support energy based routing path selection as they are not energy adaptive A new energy Adaptive routing mechanism based on AODV is proposed in this paper which selects the path based on node energy It calculates the remaining energy levels of the nodes before they are selected for routing path A threshold value is defined and nodes are considered for routing only if its energy level is above this threshold value This enforces a fair energy consumption rule on all the nodes of the network between source and destination Another threshold value is defined which decides when to search for alternate path If during traffic forwarding a node energy level falls below this threshold value, then the node search for its neighbour with high energy and bypass the traffic to the selected neighbour This will keep the node from complete battery drain condition and increase the network lifetime The proposed algorithm also drops some of the unnecessary RREQ randomly based on neighbour count of a node, which further reduce energy consumption of nodes and also reduce congestion during Route Discovery process without affecting the Performance of the routing protocol The proposed IE-AODV (Improved Energy) is implemented in NS2 simulator The simulation results have shown an increase in PDR, decrease in delay and throughput is maintained without inducing any significant overhead The proposed IE-AODV provides more consistent and reliable data transfer compared to general AODV with less average energy consummation

TL;DR: The Atal Bihari Vajpayee government had proposed to reduce government holding in state-run banks to 33% but the amendment could not be passed in Parliament as Congress, which was the main opposition party, blocked the move as discussed by the authors.
Abstract: Both Disinvestment and Privatization process in Public Sector Banks initiated by the then NDA Government came to an end soon after UPA Government took over. The Atal Bihari Vajpayee government had proposed to reduce government holding in state-run banks to 33% but the amendment could not be passed in Parliament as Congress, which was the main Opposition party, blocked the move. Later on Congress party with other partners came to power and even The Ministry of Disinvestment was closed .The recommendations of Disinvestment Commission could not be implemented. For last one decade disinvestment process came to a grinding halt, however, now again there are possibilities that Public Sector Banks may initiate the process again. Privatization process may seem to be a remote possibility at present, however, Disinvestment is on agenda of present government. The Government is now set to reduce shareholding to less than 52% while maintaining ownership but selling additional shares which will infuse more capital to fulfil capital adequacy norms as per Basel III. There are a number of challenges to this process and it is necessary to expedite the process. It is assumed that disinvestment process will make public sector banks more accountable and also efficiency may improve, ultimately pave way for privatization in near future.
