A BIOECONOMIC ANALYSIS OF THE NORWEGIAN SPRING SPAWNING HERRING (NSSH) STOCK

A biological model belonging to the Beverton-Holt age-structured family for the Norwegian spring spawning herring (Clupea harengus) (NSSH) is simulated, the outcome of which compares well with actual data on the fishery. This model is then combined with an economic model to help investigate how optimal a management policy of constant fishing mortality will be for a fishery such as the NSSH, which has a highly fluctuating stock biomass. For the range of constant values of fishing mortality explored, and a simulation time horizon of 20 years, a constant fishing mortality of 0.15 turns out to be economically optimal. It should be noted that this result is sensitive to variations in the assumptions underlying key variables of the fishery. For example, when a constant rather than variable recruitment was assumed, a different optimal fishing mortality rate was obtained.bioeconomic model, herring optimal management, Resource /Energy Economics and Policy, Q57, Q22, Q28,

Development and Analysis of Dynamic Time Based Pricing Scheme, RTFPP for Residential Demand Response Program

Paper proposes fair and dynamic pricing strategy, Real Time Fair Peak Pricing (RTFPP), for residential demand response program which takes into account the intensity of increased load above baseline (must run load) of each user and charge accordingly. Proposed methodology has the potential to increase user confidence, by the induction of fairness and baseline flexibility, hence increasing participation in residential demand response programs for economic operation of system. An algorithm is developed to impose RTFPP scheme on given user, in peak periods, for billing. To show the benefits, diverse realistic user load profiles are imposed with developed algorithm in MATLAB and results are evaluated and analysed.Keywords: Load Management, Residential demand response Dynamic time based pricing Demand side managemen

Muslims and Buddhists interaction in Pasir Mas, Kelantan

Although Malaysia is a predominantly Muslim country, other religions such as Buddhism, Hinduism, Christianity, Sikhism, Taoism, and other traditional belief systems are also practiced. The objective of this study is to explore the relationship or religious interaction between Muslims and Buddhists in one of the east coast states in Malaysia, Kelantan. A small town, Pasir Mas is chosen as it consists of two major religions, Islam and Buddhism, forming two religious communities living side by side in a traditional village namely Kg. Tendong. It is an ethno-religious study of Malay Muslims and Chinese as well as Siamese Buddhists in terms of their religious interaction in the said location. The study in Pasir Mas could be perceived as a subset study over the dominant set of ethnic groups in Malaysia. In order to measure the quality of interaction, some indicators have been prepared to be applied on a total of one hundred and forty (140) respondents that were drawn from Muslims and Buddhists. The sample size together with the above-mentioned indicators showed that the quality of interaction is encouraging in the sense that the universal values of the two religions, namely Islam and Buddhism that bind people together. On the other hand, the discouraging factor of interaction among the residents of Pasir Mas was that trivial issues of religious differences. Therefore, the significance of the study lies mainly in showing the level of interaction between Muslims and Buddhists in Pasir Mas. This result is essential to the policy makers to develop a better pattern of inter-racial interaction in a remote area of Peninsular Malaysia. The study finally discusses the need for broader and more comprehensive research in this area

Optimal Recloser Setting, Considering Reliability and Power Quality in Distribution Networks

International audienceReclosers and fuses are the commonplace protective devices in distribution networks. A recloser can prevent long-time outages by clearing temporary faults before operation of the fuses in the system. Thus, it decreases the rate of long-term outages and improves system reliability and power quality. Despite positive features of reclosers, each operation of a recloser causes a momentary voltage interruption that exacerbates power quality. Nowadays, power quality issues have become more important because of the increasing use of sensitive equipment to voltage interruptions. According to the mentioned concerns, it seems necessary to set reclosers to strike a balance between power quality and the effectiveness of fuse saving scheme. Thus, we proposed a method to set reclosers. Due to the random nature of faults, the proposed method is stochastic based on the Monte Carlo method. The proposed method determines the optimal number of operations, reclosing intervals, and protection zones. The proposed method efficiency is evaluated according to the simulation results, and the proposed method is capable of establishing an optimal trade-off between power quality and protection efficiency

Auto-Configuration of ACL Policy in Case of Topology Change in Hybrid SDN

© 2016 IEEE. Software-defined networking (SDN) has emerged as a new network architecture, which decouples both the control and management planes from data plane at forwarding devices. However, SDN deployment is not widely adopted due to the budget constraints of organizations. This is because organizations are always reluctant to invest too much budget to establish a new network infrastructure from scratch. One feasible solution is to deploy a limited number of SDN-enabled devices along with traditional (legacy) network devices in the network of an organization by incrementally replacing traditional network by SDN, which is called hybrid SDN (Hybrid SDN) architecture. Network management and control in Hybrid SDN are vital tasks that require significant effort and resources. Manual handling of these tasks is error prone. Whenever network topology changes, network policies (e.g., access control list) configured at the interfaces of forwarding devices (switches/routers) may be violated. That creates severe security threats for the whole network and degrades the network performance. In this paper, we propose a new approach for Hybrid SDN that auto-detects the interfaces of forwarding devices and network policies that are affected due to change in network topology. In the proposed approach, we model network-wide policy and local policy at forwarding device using a three-tuple and a six-tuple, respectively. We compute graph to represent the topology of the network. By using graph difference technique, we detect a possible change in topology. In the case of topology change, we verify policy for updated topology by traversing tree using six-tuple. If there is any violation in policy implementation, then affected interfaces are indicated and policies that need to be configured are also indicated. Then, policies are configured on the updated topology according to specification in an improved way. Simulation results show that our proposed approach enhances the network efficiency in term of successful packet delivery ratio, the ratio of packets that violated the policy and normalized overhead

Factors Affecting Secondary School Principals’ Time Management Practices in Khyber Pakhtunkhwa

This study sought to investigate whether principal’s age, gender, administrative experience, training in time management area, school’s nature, level, location and complexity has any effect on the time management practices. Six time management practices used by secondary school principals i.e. scheduling contacts, managing meetings, delegating tasks, setting priorities, managing paperwork, handling interruptions were incorporated in a questionnaire. A questionnaire was designed, validated and administered to respondents for collecting data having Cronbach Alpha value of 0.864. Data were collected from 344 secondary school principals selected through stratified random sample from seven divisional headquarter districts of Khyber Pakhtunkhwa. Results show that principal’s administrative experience and school’s level have significant effect on principals’ time management practices. Whereas principal’s age, gender, training in time management area, school’s nature, location and complexity have no significant effect on principals’ time management practices. It was recommended that introductory courses, refresher courses, workshops, and seminars on time management practices should be included in in-service training program for principals to equip them with skills, knowledge and attitude on adequate time management practices regardless of their personal characteristics and school’s level, location, nature and complexity
