The prevalence of cloud computing environments and the ever increasing reliance of large organisations on computational resources has meant that service providers must operate at unprecedented scales and levels of efficiency. Dynamic resource allocation (DRA) policies have been shown to allow service providers to improve resource utilisation and operational efficiency in presence of unpredictab...

As the foundation for MapReduce processing, Hadoop is one of the fundamental technologies in big data analytics. Hadoop breaks up large data into data blocks, replicates them, and stores them in a distributed storage system. Data blocks can be placed in a machine where the data will be processed (data local), in a machine in the same rack (rack-local), or in a machine in a different rack (off-r...

India is the second largest bicycle manufacturer in the world, next only to China. The Chinese bicycle industry has already been successful in cornering almost 25 per cent share in fancy bicycle market in India which is a major cause of worry for the small-scale bicycle parts manufacturers in India. An attempt has been made to provide a comprehensive framework for the selection process of bicyc...

Demarcating on-street bicycle facilities is oftenmentioned as an important strategy to encourage increased bicycle safety and bicycle travel. However, little if any literature has focused on instances where separate onstreet bicycle facilities end. This paper better understands the severity of such instances and corresponding physical characteristics. We identify 30 discontinuities of on-street...

In this paper, a Fuzzy Inference System (FIS) is fabricated on a riderless bicycle. The Fuzzy Inference System is based on a rule base inherited from human experience of bicycle riding. The steady turning motion and roll-angle tracking controls for the riderless bicycle were achieved by using fuzzy concept. Collection of sensors, actuator, micro-controller and electrical circuits were employed ...

Abstract. In his study of quantum groups, Drinfeld suggested to consider set-theoretic solutions of the Yang–Baxter equation as a discrete analogon. As a typical example, every conjugacy class in a group, or more generally every rack Q provides such a Yang–Baxter operator cQ : x ⊗ y 7→ y ⊗ x . In this article we study deformations of cQ within the space of Yang–Baxter operators. Over a complete...

A rack of order n is a binary operation B on a set X of cardinality n, such that right multiplication is an automorphism. More precisely, (X,B) is a rack provided that the map x 7→ x B y is a bijection for all y ∈ X, and (x B y) B z = (x B z) B (y B z) for all x, y, z ∈ X. The paper provides upper and lower bounds of the form 2cn 2 on the number of isomorphism classes of racks of order n. Simil...

Caroline is a wine buff and bon vivant. She likes to stop at her local wine store, Transcendental Tastings, on the way home from work. She browses the aisles looking for the latest releases from her favorite vineyards. Occasionally she picks up a few bottles. She stores these in a rack in a cool corner of her cellar. She and her partner eat out frequently but when they are at home they usually ...

The population of Bangladesh is increasing tremendously and to keep pace with the increasing demand of fish protein, farmers intensified fish production from the water bodies which created environmental pollution. To tackle the situation the raft and rack aquaponics experiment was conducted to reduce the water pollution and have vegetable production from high density poly-culture fish ponds. Th...
