The study investigates apartment’s façade thermal performance with neo-minimalist architectural style in Penang, Malaysia. Neo-minimalist style is considered as the most popular style in Malaysia in 2010s. The style is rediscovering from early modern minimalist movement with a design concept “less is more”. It applies minimal and efficient design of architectural character in defining form and space. Penang Island the second most important city in Malaysia after Kuala Lumpur. It is located at the north-western part of the country. The first case studies is the Light Linear apartment which has sixteen stories located on the east cost of Penang Island at Pantai Street, Penang. The second case study is BayStar apartment building, the eleven stories building tis located in Bayan Lepas at the seaside facing Jerejak Island. In order to conduct this study Fluke Ti20 thermal imager was used to capture thermal images for the west facades of the selected case study hourly from 12:00 to 6:00 pm on 15th March 2017. The study finds that the recessed wall, balconies and the shading devices were the important elements to provide shades on the façades for good thermal performance.

This chapter uses two case studies to explore how historians study language movement and change through comparative historical linguistics. The first case study stands as a short chapter in the larger history of the expansion of Bantu languages across eastern, central, and southern Africa. It focuses on the expansion of proto-Kafue, ca. 950–1250, from a linguistic homeland in the middle Kafue River region to lands beyond the Lukanga swamps to the north and the Zambezi River to the south. This expansion was made possible by a dramatic reconfiguration of ties of kinship. The second case study explores linguistic evidence for ridicule along the Lozi-Botatwe frontier in the mid- to late 19th century. Significantly, the units and scales of language movement and change in precolonial periods rendered visible through comparative historical linguistics bring to our attention alternative approaches to language change and movement in contemporary Africa.

The Yuan Dynasty

Since the Yuan Dynasty, the belief of Matsu had started to spread from the birthplace to the northern coastal areas in China. Matsu worship developed to the pinnacle with the official promotion on account of the government’s dependence on grain transported by sea since the mid-Qing Dynasty. A large amount of Matsu temples emerged in coastal cities of Bohai Rim where it still keeps a large number of them until now. It has much relationship between the spread of Matsu culture and the flow of Fujian population. It was one of the main building way that the Matsu temples attached to the local hall of Fujian in Bohai Rim. The Hall of Fujian in Yantai, Which was built with materials taken from Fujian, in the feature of traditional architectural style from QuanZhou, is very different from the local building style of Yantai. This case indicates that maritime culture of the south area had spread and developed in the north areas under the promotion of the population flow and the economic transaction. The essay introduces briefly about the development of Matsu culture in Bohai Rim and takes the case study of the Hall of Fujian in Yantai analyzing its causes and features, and the value as Matsu heritage. Then the paper will discuss the conservation of Matsu culture mere include the tangible and the intangible culture heritage around the origin area, the heritages of the spread area also have the same importance significance. With the evolution of the society, it calls urgent attention and protection of Matsu culture in Bohai Rim.

This essay examines the issue of missing heritage, cultural identity, and regeneration of two historically marginalised communities in the Humber River Basin region of western Newfoundland, Canada: Woods Island and Crow Gulch. This region was shaped by the implementation of international treaties which restricted settlement until the turn of the twentieth century by Britain, France and the United States. The first case study focuses on a former fishing community in the Bay of Islands, Woods Island, whose prosperity once coincided with the need by large fish producers based in Gloucester, Massachusetts; they relied on the Bay of Islands for a herring bait fishery to conduct their operations, making the location one of the most important sources of supply in the North Atlantic. Issues surrounding treaty rights and access to this region’s resources resulted in international arbitration and The Hague Tribunal of 1910, and set a legal precedent for opening up global access to the world’s oceans. A half-century later, in the face of the forces of ‘modernisation’, Woods Island was resettled under pressure from the Newfoundland government, as part of a larger strategy to transform the island’s society and economy. Its heritage remains however important to former residents and their families in understanding a world now lost. The second case study explores an abandoned underclass community, consisting mostly of residents with French/Aboriginal background who were largely discriminated against because of their ethnicity. While also no longer in existence, Crow Gulch in its iconic role is significant in the wake of a recent major Mi’kmaw resurgence in Western Newfoundland. Together, these studies demonstrate how to conserve tangible and intangible culture of marginalised communities by linking micro-history to macro-history and how to preserve the past for future cultural benefit.

Management Procedure

Bycatch, the undesirable and non-intentional catch of non-target species in marine fisheries, is one of the main causes of mortality of marine mammals worldwide. When quantitative conservation objectives and management goals are clearly defined, computer-based procedures can be used to explore likely population dynamics under different management scenarios and estimate the levels of anthropogenic removals, including bycatch, that marine mammal populations may withstand. Two control rules for setting removal limits are the Potential Biological Removal (PBR) established under the US Marine Mammal Protection Act and the Removals Limit Algorithm (RLA) inspired from the Catch Limit Algorithm (CLA) developed under the Revised Management Procedure of the International Whaling Commission. The PBR and RLA control rules were tested in a Management Strategy Evaluation (MSE) framework. A key feature of PBR and RLA is to ensure conservation objectives are met in the face of the multiple uncertainties or biases that plague real-world data on marine mammals. We built a package named RLA in the R software to carry out MSE of control rules to set removal limits in marine mammal conservation. The package functionalities are illustrated by two case studies carried out under the auspices of the Oslo and Paris convention (OSPAR) (the Convention for the Protection of the Marine Environment of the North-East Atlantic) Marine Mammal Expert Group (OMMEG) in the context of the EU Marine Strategy Framework Directive. The first case study sought to tune the PBR control rule to the conservation objective of restoring, with a probability of 0.8, a cetacean population to 80% of carrying capacity after 100 years. The second case study sought to further develop a RLA to set removals limit on harbor porpoises in the North Sea with the same conservation objective as in the first case study. Estimation of the removals limit under the RLA control rule was carried out within the Bayesian paradigm. Outputs from the functions implemented in the package RLA allows the assessment of user-defined performance metrics, such as time to reach a given fraction of carrying capacity under a given level of removals compared to the time needed given no removals.

First Case

Renewable resources gained more attention in the last two decades due to persisting energy demand coupled with decrease in fossil fuel resources and its environmental effect to the earth. In this work, two cases of hybrid system will be studied. The first one dr. Jawad's home (Assistant professor in Electrical Engineering Department- University of Basrah). It is located in Al-Jazeera area that adjacent to the coast of the Shatt al – Arab that is located about 34 km south of the city center and its coordinates are (30.12° N, 47.49° E) latitude and longitude respectively. He used a hybrid system consist of (PV panels-batteries and the wind power will be studied theoretically by suggests a 4.5kW) wind turbine system) to feeding home's load. The second case study is the laboratories of the Department of Electrical Engineering-University of Basrah.The Department located in Garmat Ali district (part of Al-Hartha area) that is located in the north east of Basrah city and its coordinates are 30.582° N latitude and 47.76° E longitude. The hybrid system that used in this department consists of (PV panels-batteries). Results showed from first case study that the total power saving when using hybrid system resources in the house that consume 33.24 MWh/year about 31.3% by providing 10.4 MWh/year. Through the study of the laboratories of the Department the results show that is possible to operate many electrical appliances at the same time depending on the hybrid system such as fans, lighting, and computers and it is noted that the air conditioners can be operated by using more and more solar cells and batteries.

Abstract Maintaining well integrity is critical to sustaining production from mature and aging fields. Disposable fibre optic technology has been deployed in wells in the North Sea to locate known tubing leaks in the completion. The disposable fibre optic intervention system releases a probe into the well to enable the deployment of bare fibre optic line. The fibres are released from the probe as it descends into the well. In the presented case study, the probe contained both single-mode and multi-mode fibre optic lines to enable simultaneous Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS) surveys to be performed. Once deployed in the well, pressure manipulation programs were performed to activate any tubing or casing leaks while acquiring DTS and DAS data. As a result of the exceptional sensitivity of the bare fibres and the effective coupling of the fibre with the tubing wall the technology is shown to be highly effective in detecting leaks and confirming barrier integrity. In the presented example a leak was located along with the direction and rate of the fluid movement in the ‘B’ annulus. The simplicity of the system and highly efficient operations greatly reduced survey times in comparison to conventional intervention techniques thereby greatly reducing the cost of intervention. It can be demonstrated that the disposable fibre optic deployment system provides a game changing and cost-effective solution for both leak detection and determining liquid levels in the wells. The disposable fibre solution is a unique deployment method which provides an alternative to conventional well surveys, reducing the complexity, time and cost to acquire valuable distributed well data. This is the first case history published for this technology in leak detection application.

Abstract. Quasi-periodic Pc 5 pulsations have been reported inside and just outside the Earth's magnetotail during intervals of low geomagnetic activity. In order to further define their characteristics and spatial extent, we present three case studies of simultaneous magnetic field and plasma observations by IMP-8, ISEE-1 (and ISEE-2 in one case) in the Earth's magnetotail and ISEE-3 far upstream of the bow shock, during intervals in which the spacecraft were widely separated. In the first case study, similar pulsations are observed by IMP-8 at the dawn flank of the plasma sheet and by ISEE-1 near the plasma sheet boundary layer (PSBL) near midnight local time. In the second case study, simultaneous pulsations are observed by IMP-8 in the dusk magnetosheath and by ISEE-1 and 2 in the dawn plasma sheet. In the third case study, simultaneous pulsations are observed in the north plasma sheet boundary layer and the south plasma sheet. We conclude that the pulsations occur simultaneously throughout much of the nightside magnetosphere and the surrounding magnetosheath, i.e. that they have a global character. Some additional findings are the following: (a) the observed pulsations are mixed mode compressional and transverse, where the compressional character is more apparent in the close vicinity of the plane ZGSM=0; (b) the compressional pulsations of the magnetic field in the dusk magnetosheath show peaks that coincide (almost one-to-one) with similar peaks observed inside the dawn plasma sheet; (c) in the second case study the polarization sense of the magnetic field and the recurrent left-hand plasma vortices observed in the dawn plasma sheet are consistent with anti-sunward moving waves on the magneto-pause; (d) pulsation amplitudes are weaker in the PSBL(or lobe) as compared with those in the magneto-tail's flanks, suggesting a decay with distance from the magnetopause; (e) the thickness of the plasma sheet (under extremely quiet conditions) is estimated to be ~22 RE at an average location of (X, Y)GSM=(16, 17) RE, whereas at midnight local time the thickness is ~14 RE. The detected pulsations are probably due to the pressure variations (recorded by ISEE-3) in the solar wind, and/or the Kelvin Helmholtz instability in the low-latitude boundary layer or the magnetopause due to a strongly northward IMF.
