But integration of all these three cutting edge technologies is complex to understand. In this research we first provide a security centric view of three layered approach for understanding the technology, gaps and security issues. Then with ... View full abstract»

In this paper we present a simple control architecture of a mobile robot for the purpose of target approaching. The proposed architecture combines three separate control modules to achieve an overall robot behavior for robust target approaching in a constrained environment. The three modules are "target search", "target approach" and "fuzzy obstacle avoidance". The target search module applies a c... View full abstract»

Though an important preliminary process to diagnose cardiac abnormality, cardiac stress test is often inaccurate and involves costly follow-up procedures. Data mining based approaches have potentials to reduce the uncertainties in this respect. However, the exploration on such data mining approaches is still limited. Further, traditionally employed data mining techniques like feature selection oft... View full abstract»

This paper designs a nonlinear, time-invariant motion planner that guarantees collision-free lane changing, merging and overtaking maneuvers, whilst considering all practical limitations and constraints due to the system nonholonomy, workspace geometry, and steering specifications. The motion planner derived from the Lyapunov-based Control Scheme works within an overarching leader follower scheme.... View full abstract»

In a cloud environment, virtualization enables efficient allocation of shared set of physical resources to a large user base with different needs. This has potentially allowed clouds to deliver to its customers the benefits associated with an economy of scale. On the other hand, virtualization can introduce performance penalties as well. In this paper we present the performance of the Eucalyptus c... View full abstract»

In this paper we propose a new solution to the findpath problem of a point-mass robot which is required to move safely to a designated target in a 3-dimensional workspace. We consider a priori known workspace cluttered with obstacles of arbitrary position and size. The novelty of the solution is three-fold. Firstly, a velocity algorithm is used to drive the robot from its initial position to the t... View full abstract»

Interpreting tertiary structure of a protein has been a crucial task in the field of biosciences. This problem can be addressed by detecting protein folds which is considered as an intermediate step in the tertiary structure prediction. From the perspective of computational sciences, the protein fold recognition can be subdivided in two steps: 1) feature extraction of protein sequences, and 2) ide... View full abstract»

This paper presents results from a scoping study undertaken with the intention of demonstrating the applicability of reflectance Near-Infrared (NIR) spectroscopy in classification of pharmaceutical type based on active ingredient. The part of the process selected for the scoping study is the packaging step in the manufacturing of pharmaceuticals. The rational for the selection of the packaging ste... View full abstract»

In this paper, classification of electroencephalography (EEG) signals of motor imaginary tasks is studied using cepstrum analysis and linear predictive coding (LPC). The Brain-Computer Interface (BCI) competition III dataset IVa containing motor imaginary tasks for right hand and foot of five subjects are used. The data was preprocessed by applying whitening and then filtering the signal followed ... View full abstract»

The advanced investigation of in-store behavior has been dramatically intrigued researchers in the last decade, since the radio frequency identification (RFID) technology was introduced into the grocery stores for information acquisition via tracking the customers. Shopping carts and baskets with a small RFID tag attached are recognized as surrogates instead of enumerators to trail the customers, ... View full abstract»

This paper examines the trend in cash holdings ratios starting from the time firms have been mandatorily required to release consolidated financial statements and finds that the ratio is increasing every year. We also investigate whether this increasing trend varies by firm size and show that the tendency to hold cash strengthens as firm size becomes smaller. Moreover, when considering the determi...

The category Rel of sets and relations intimately ties the notions of function, partial multivalued function, and direct image under a function through the description of Rel as the Kleisli category of the covariant power set functor on Set. We present a suitable framework to obtain a similar relationship between the concepts of functor, partial multivalued functor, and the direct image under a fu... View full abstract»

Common themes in urban development worldwide are "smart" cities initiatives with high dependency and application of ICT technologies, which leads not only to superior and rational optimization of time and resources but to build the whole smart city ecosystem. However, the definitions of "smart" cities remain vague, with lack of holistic strategic framework to assist decision makers to avoid any po... View full abstract»

With continual changes made and reviews of the exchange rate regime of Solomon Islands it is imperative that a proper forecasting modelling tool is established. The use of neural network models in exchange rate forecasting has received much attention in recent research. In this paper we propose an artificial neural network (ANN) model for forecasting exchange rates of the Solomon Islands dollar (S... View full abstract»

Material Flow Cost Accounting (MFCA) is a Environmental Management Accounting tool, targeting simultaneously to increasing profit and at the same time reduce environmental impacts. In 2011, the fundamental framework of MFCA was published by the International Organization for Standardization (ISO) within the 14000ff family on Environmental Management [3]. The MFCA analysis shows material loss in pr... View full abstract»

Collaborative Filtering (CF) is one of the most commonly used and successful recommendation techniques. The performance of traditional collaborative filtering is limited by the sparsity of data, and relies on explicit user feedbacks (ratings). However, the growing number of products and users will leave the user-item matrix sparser, and high-quality explicit feedbacks are not always available. In ... View full abstract»
