In general business insurance, the maximum accumulated amount of losses retained by the insured under deductible policy modifications is usually set as part of the terms and conditions of the policy documents. However, the risk retention of the insured under deductible is limited for every loss event and on a yearly arrangement. A policy without deductible coverage modifications may encounter excessive large claim amount. The insurer only takes over payment of claims given that the aggregate limit is exceeded. This paper develops an analytical framework for evaluating the effect of structural properties of dirac-delta on insurance risk variables with deductible clauses. The aim is to derive models for the moments and variance of insurance claim size in a loss event. In order to achieve this and create analytically sound and useful theoretical basis of investigating actuarial risk functions, the general properties of dirac-delta is first examined in respect of probability density function after some operations. We then obtained insurance claim severity and variance models for an arbitrary policy in general insurance business under deductible coverage modifications which is meant to disapprove nuisance claims and control problem of moral hazard. The results have been clearly stated and proved as part of our findings which may have significant implications on policy underwriting efficiency and decisions.

Cardiff Bay, one of the largest man-made freshwater lakes in Europe, was formed in April 2001 when two of the main rivers in South Wales, United Kingdom were impounded by the construction of a barrage. The water quality of Cardiff Bay has been intensively monitored, primarily due to the wetland reserve which was undergoing a fairly steady succession from the previous estuarine habitat. The present study was carried out to investigate the physical, chemical and biological quality of water in Cardiff Bay. Seven water quality parameters namely pH, biochemical oxygen demand (BOD), Ca, Mg, Cl, total hardness and total suspended solids (TSS) were analyzed for a period of five years from 2001 to 2005 to investigate their temporal variation in this study. The findings indicated that variations in water quality across Cardiff Bay were small during this period. In general, pH, BOD, Ca and
hardness showed a slightly increasing trend as opposed to Cl which decreased. Mg was temporally homogeneous and TSS varied inconsistently. A comparative study was conducted against the relevant data obtained from Sasthamcotta Lake in Kerala, India in which higher
values of pH, Ca and Mg were observed in Cardiff Bay. The necessity for long-term data sets was highlighted due to the observed lack of correlation among the indicators, which therefore suggests that a long-term monitoring is imperative in assessing the water quality trend as well as management strategies.

Barua, Saurav; Sultana, Rabaka
Seismic load is crucial for the structural design of multistoried buildings. The study delves to
evaluate performance of core wall in the building frame under seismic loading. Two models are compared in this research. One is typical frame structure without any shear wall i.e. model 1 and another one is frame structure with core wall, i.e. model 2. The study found that frame structure with core wall (model 2) have much lower story drift in comparison with frame structure without shear wall (model 1). Vis-à-vis, frame structure with core wall (model 2) experiences lower column reactions, shear forces, base shear and overturning moments compare to the frame structure without shear wall (model 1) under seismic load. Therefore, the core wall incorporated in multistoried building plan can against withstand seismic load with better performance.

The study is to find out changes in weight of cotton knit fabrics in pretreatments of dyeing. Single jersey, single lacoste, 1x1 rib, 1x1 lycra rib, 2x2 rib & terry fabrics were used for this research and processed them in different pretreatments of dyeing. Standard recipes were followed with right chemicals were used in every stage. All the processes were conducted in a reputed industry and modern machines were used at every process. After values of weight changes at each stage were carefully measured maintaining same atmospheric condition. It was found that weight changing rate is different for the different knit structured fabric though same recipes and procedures were followed for all of the fabric samples in a
particular stage. Finally, the reasons of variation in weight change were explained logically.
