Purpose: The purpose of this paper is to study the effects of dimple geometries and arrangements on the heat transfer enhancement in a dimple jacketed heat exchanger. Design/methodology/approach: For the purpose of this paper, with the experimental validated numerical model, this paper carries out numerical simulations of both single dimples with different geometries and the whole dimple jacketed

This thesis deals with the enforcement of intellectual property rights as an abuse of dominance. In particular after refusal to license a patent, which is essential for a standardized technology. Seeking for injunction relief may in some circumstances violate applicable competition law. The analysis will provide a hint, whereas patent holder who is dominating in particular market can or should be

Uppsatsen syftar till att söka förståelse till varför tvister mellan fackförbund om vem som ska teckna kollektivavtal uppstår. Arbetsmarknadernas parter är i allmänhet ense om att det som regel bör finnas ett kollektivavtal på varje avtalsområde. Kollektivavtalets speciella rättsverkningar gör det viktigt för fackförbunden att vara avtalspart i ett kollektivavtal. Kollektivavtalet sätter i stor utThe aim of this essay is to seek understanding about why conflicts appear between trade unions regarding which one of them should sign the collective agreement in the workplace. The labour market parties are in general in an agreement that there should only be one applicable collective agreement in every area of work. The unique effects of the collective agreement make it crucial for the trade uni

Current trends show that the number of people affected by natural disasters is likely to increase in coming decades. Today, more than half the world's population lives in cities and the number is expected to rise in the future. To make cities safe is therefore vital. Making Cities Resilient is an ongoing global campaign in the area of disaster risk reduction and aims to build resilient cities

The aim of this qualitative study was to investigate the social identity of students at upper secondary school for physically disabled students. The youths I drew my attention to suffered from severe physical disabilities and therefore received specially adapted education in small classes, but integrated at an ordinary upper secondary school. By "social identity" I mean how the students

The literature on regional innovation systems emphasizes the role of the region as locus for interactive learning and knowledge exchange, stressing the importance of (geographical) proximity for innovation. Even though the importance of extra-regional knowledge is widely acknowledged, there has been only little emphasis on the particular role and the nature of global knowledge flows. The aim of th

BackgroundNursing home residents in Sweden are old, frail and usually have multiple morbidities which often make dying a prolonged suffering. It has been found that older persons at nursing homes receive far less palliative care than younger persons, partly because it is difficult to identify when the final stage of life begins. The identification may help the staff to enable the older person and

Due to the possibility of increased efficiency and reduced emissions, Homogeneous Charge Compression Ignition (HCCI) is a promising alternative to conventional internal combustion engines. Ignition timing in HCCI is highly sensitive to operating conditions and lacks direct actuation, making it a challenging subject for closed-loop control. This paper presents physics-based, control-oriented modeli

In temperate regions, many vector-borne parasites maximise their transmission prospects by adjusting reproduction to seasonal cycles of host susceptibility and vector availability. Nevertheless, in these regions there are areas where environmental conditions are favourable throughout the year, so that parasites could benefit from a year-round transmission strategy. We analysed how different transm

Safe languages like Java provide a much more programmerfriendly environment than the low-level languages in which real-time and embedded software have traditionally been implemented. However, an obstacle for widespread use of Java in control applications has been the predictability and real-time performance of garbage collection, and the cumbersome memory management associated with RTSJ NoHeapReal

Christian Zionism is usually characterized as a theological and political movement grounded in literalist bible hermeneutics and End-time speculations that dedicate unwavering support to the State of Israel and the Jewish people. The prophetic element in Christian Zionism has in later years been downplayed for a more down-to-earth focus on social and political commitment to the well-being of the s

Enzymatic pretreatment of algae by means of cellulose degrading enzyme was evaluated through lab-scale and pilot-scale experiments. The degradation efficiency of the enzyme depended on the initial physical quality of the algae. Lab-scale batch anaerobic digestion experiments showed comparatively low methane potential for the pretreated algae at both mesophilic and thermophilic temperatures. Howeve

This paper presents an adaptive video encoder that can be used to compare the behavior of different adaptation strategies using multiple actuators to steer the encoder towards a global goal, composed of multiple conflicting objectives. A video camera produces frames that the encoder manipulates with the objective of matching some space requirement to fit a given communication channel. A second obj
