A Refined Understanding of Cost-Optimal Planning with Polytree Causal Graphs

Complexity analysis based on the causal graphs of planning instances has emerged as a highly important area of research. In particular, tractability results have led to new methods for the identification of domain-independent heuristics. Important early examples of such tractability results have been presented by, for instance, Brafman &amp; Domshlak and Katz &amp; Keyder. More general results based on polytrees and bounding certain parameters were subsequently derived by Aghighi et al. and Ståhlberg. We continue this line of research by analyzing cost-optimal planning restricted to instances with a polytree causal graph, bounded domain size and bounded depth (i.e. the length of the longest directed path in the causal graph). We show that no further restrictions are necessary for tractability, thus generalizing the previous results. Our approach is based on a novel method of closely analysing optimal plans: we recursively decompose the causal graph in a way that allows for bounding the number of variable changes as a function of the depth, using a reording argument and a comparison with prefix trees of known size. We can then transform the planning instances into constraint satisfaction instances; an idea that has previously been exploited by, for example, Brafman &amp; Domshlak and Bäckström. This allows us to utilise efficient algorithms for constraint optimisation over tree-structured instances.
Adaptability and applicability of Need Hierarchy Theory in assessing employee satisfaction with special reference to EPC Company of UAE

Any research on studying employee satisfaction always looks afresh and same is the case with the research work made by Abraham Maslow in assessing and analysing the needs of human beings. It is a popular theory in the field of motivation and pioneer for other research works to explore further in assessing the satisfaction levels of employees. In today's millennium HR environment a large number tools and tests are available to assess and measure the satisfaction level of an employee yet employers are interested to go through the gross root level of finding the reasons, what makes an employee more satisfied. The current research study is made basically to cater to the needs of employers, analysts, academicians, researchers, practitioners, HR managers and critics, etc., to visualise the application of need hierarchy theory of motivation in assessing employee satisfaction using ethnography method.
Assisted Navigation Algorithm for Wireless Sensor Actuator and Robot Networks

Wireless Sensor, Actuator and Robot Networks (WSARNs) are made of mobile and static sensor nodes that interact in order to collaboratively perform specific tasks, such as supporting assisted navigation for mobile robotic nodes that carry out requested operations in hostile environments, where the human presence is impracticable. In this regard, it is worth noting that assisted navigation algorithms have a highly dynamic nature, and are implemented by sensor nodes that are characterized by limited transmission power and lean autonomy in terms of computing and memory capacity. This paper presents an improved version of the assisted navigation algorithm based on the concept of “credit field”. The main aim of the proposed algorithm is to reduce and balance the energy consumption among the static sensor nodes when running the algorithm to manage the presence of obstacles and adversary areas, thus extending the lifetime of WSARNs. The algorithm has been tested on a hybrid sensor network that employs Mica2 Motes as static sensor nodes and Lego Mindstorms robots integrated with a Stargate board developed by Crossbow as mobile nodes.
Bounded Suboptimal Game Tree Search

Finding the minimax value of a game is an important problem in a variety of fields, including game theory, decision theory, statistics, philosophy, economics, robotics, and security. Classical algorithms such as the Minimax algorithm can be used to find the minimax value, but require iterating over the entire game tree, which is in many cases too large. Alpha-Beta pruning identifies portions of the game tree that are not necessary for finding the minimax value, but in many cases the remaining part of the game tree is still too large to search in reasonable time. For such cases, we propose a class of algorithms that accepts a parameter e and returns a value that is guaranteed to be at most e away from the true minimax value. We lay the theoretical foundation for building such algorithms and present one such algorithm based on Alpha-Beta. Experimentally, we show that our algorithm allows controlling this runtime/solution quality tradeoff effectively.
Pipel: Exploiting Resource Reorganization to Optimize Performance of Pipeline-Structured Applications in the Cloud

Workflow has become a standard for many scientific applications that are characterized by a collection of processing elements. Particularly, a pipeline application is a type of workflow that receives a set of tasks, which must pass through all processing elements in a linear fashion. However, the strategy of using a fixed number of resources can cause under- or over-provisioning situations, besides not fitting irregular demands. In this context, our idea is to deploy the pipeline application in the cloud, so executing it with a feature that differentiates cloud from other distributed systems: resource elasticity. Thus, we propose Pipel: a reactive elasticity model that uses lower and upper load thresholds and the CPU metric to on-the-fly select the most appropriated number of compute nodes for each stage along the pipeline execution. The results were promising, presenting an average gain of 38% in the application time when comparing non-elastic and elastic executions.
Speech to Text Conversion System for Myanmar Alphabet

This paper is aimed to implement the speech to text conversion system for Myanmar alphabet. The Myanmar alphabet consists of 33 characters from ?ka? to ?ah?. The proposed system is software architecture which allows the user to speak against the computer in Myanmar language and the corresponding character is printed on the screen in the Microsoft Office Word Document Format. The system is emphasized on Speaker Independent Isolated Word Recognition System. The proposed system directly acquires and converts speech to text. This system contains two main modules: feature extraction and feature matching. Mel Frequency Cepstrum Coefficients (MFCC) is applied for feature extraction which extracts a small amount of data from the voice signal that can later be used to represent each character. Feature matching involves the actual procedure to identify the unknown character by comparing extracted features from the voice inputs of a set of known characters. In this system, Vector Quantization (VQ) approach using Linde, Buzo and Gray (LBG) clustering algorithm, which reduces the amount of data and complexity, is applied for feature matching. To implement this system MATLAB programming language is used.

A generic construction of identity-based proxy signature scheme in the standard model

Recently, numerous identity-based proxy signature (IDPS) schemes are constructed by direct methods or generic methods. However, most of them are proved only to be secure in the random oracle model or are involved high computational cost. In this paper, we present a novel and generic construction method of IDPS scheme secure in the standard model from any identity-based signature (IDS) scheme. The security of IDPS scheme constructed by our method is based on the security of original IDS scheme. The computational cost of constructing an IDPS scheme is almost the same as that of constructing an original IDS scheme. Compared with other existing IDPS schemes constructed by direct methods or other generic methods, our IDPS scheme has better performance: signature length and computational cost of our IDPS scheme are almost half of other existing IDPS schemes. What is more, our method can be applied to construct other identity-based proxy cryptosystems.
A COMPARATIVE ANALYSIS OF VECTOR AUTOREGRESSIVE MODEL AND NEURAL NETWORKS

In this work, vector autoregression and neural network approach to multivariate time series analysis is presented. A vector autoregressive model and multilayer perceptron network with back-propagation, gradient descent algorithm have been designed to model the monthly average exchange rates of three international currencies with respect to naira. The series span over the period of January, 2012 to August, 2017. The original series were preprocessed to smoothen the distribution and facilitate fast convergence in the network algorithm. In training the network to learn the combined series of the exchange rates, a remarkable achievement was made. Adding to the beauty of the network model is the fact that the number of units of the input layer was predetermined through the VAR model. Using some model performance measures (RMSE, MBE and R2), it was recorded that the neural network approach performs better than the VAR model as it yielded minimum error of prediction.
A novel authentication scheme for anonymity and digital rights management based on elliptic curve cryptography

As the internet makes data transmission easy and fast, digital contents of all kinds can be spread all over the world at a shocking speed. Along with such amazing swiftness and convenience, however, modern computer and communication technologies have also brought various kinds of issues associated with digital rights management. Digital rights management (DRM) systems are access control technologies used to restrict the use, modification, and distribution of proprietary hardware and copyrighted works. Now, in view of modern people's heavy dependence on their mobile devices, we consider it a good idea to design a DRM scheme on the basis of elliptic curve cryptography (ECC). In this paper, we shall review Amin et al.'s (2016) scheme and point out some security weaknesses we have found. Then, with the security flaws mended, we shall propose an improved ECC-based protocol for DRM that is especially suitable for applications on mobile devices.
The supersingularity of Hurwitz curves

We study when Hurwitz curves are supersingular. Specifically, we show that the curve $H_{n,\ell}: X^nY^\ell + Y^nZ^\ell + Z^nX^\ell = 0$, with $n$ and $\ell$ relatively prime, is supersingular over the finite field $\mathbb{F}_{p}$ if and only if there exists an integer $i$ such that $p^i \equiv -1 \bmod (n^2 - n\ell + \ell^2)$. If this holds, we prove that it is also true that the curve is maximal over $\mathbb{F}_{p^{2i}}$. Further, we provide a complete table of supersingular Hurwitz curves of genus less than 5 for characteristic less than 37.

The model to evaluate is a model for the preservation of digital evidence-based institutions of criminal investigations where it is essential to preserve evidence that has characteristics of the environment with the purpose of increasing the rate of admissibility of the evidence in court. This article aims to evaluate the model and its impact in terms of security, admissibility, and long-term preservation characteristics. We respond to the following research question: Does the model, implemented in a software application for a case study, raise the admissibility of digital evidence in court? Thus, a software application is developed, the unit of study is defined, and the results are analysed. The study determined that the model, when implemented properly and following the guidance of implementation of the model, raises the admissibility of digital evidence in court.
Bone- and air-conduction speech combination method for speaker recognition

In this paper, first, we report speaker recognition performance using bone-conduction speech based on an i-vector-based speaker recognition system, which is the current state-of-the-art method. In addition, we propose three speaker recognition methods combining bone-conduction speech and air-conduction speech: a feature combination method, a speaker model combination method, and a similarity score combination method. To evaluate the proposed methods, we conducted speaker recognition experiments using a part of a large speech corpus constructed by the National Research Institute of Police Science, Japan. Experimental results show the bone-conduction speech performs almost the same as the air-conduction speech when the enrolment data and evaluation data are collected in the same session. In addition, all proposed methods improved the speaker recognition performance of air- and bone-conduction speech in the experiments. From these results, we conclude that fusing air- and bone-conduction speech improves the speaker recognition performance.
A survey on different continuous authentication systems

There has been significant research in the provision of trustworthy initial login user authentication, however, there is still need for continuous authentication during a user session. Most mobile devices and computer systems authenticate a user only at the initial login session and do not take steps to recognise whether the present user is still the initial authorised user or an imposter pretending to be a valid user. Therefore, a system to check the identity of the user continuously throughout the whole session is necessary. To ensure the authenticity of the user during their whole login session, a continuous user authentication mechanism is required. In this paper, an overview of different continuous authentication methods is presented along with a discussion on the merits and demerits of the available approaches. This paper also discusses the understanding of the emerging necessities and open problems in continuous user authentication system.
