In gaze controlled computer interfaces the dwell time is often used as selection criterion. But this solution comes along with several problems, especially in the temporal domain: Eye movement studies on scene perception could demonstrate that fixations of different durations serve different purposes and should therefore be differentiated. The use of dwell time for selection implies the need to distinguish intentional selections from merely per-ceptual processes, described as the Midas touch problem. Moreover, the feedback of the actual own eye position has not yet been addressed to systematic studies in the context of usability in gaze based computer interaction. We present research on the usability of a simple eye typing set up. Different dwell time and eye position feedback configurations were tested. Our results indicate that smoothing raw eye position and temporal delays in visual feedback enhance the system's functionality and usability. Best overall performance was obtained with a dwell time of 500 ms.

<p><span>This paper proposes a steady-state of the Static Var Compensator (SVC) &amp; Thyristor Controlled Series Capacitor (TCSC) set up for enhancing the damping overall performance and growing the integral clearing time (CCT) of a power network. The indispensable clearing time is carried out through increasing the time fault interval until the gadget loses stability. Increasing the CCT can be contribute to reliability of the safety gadget, decrease the protection machine ranking and cost. In order to attain most enhancement of machine stability via optimizing location, sizing and control modes of SVC and TCSC. Models and methodology for putting and designing shunt FACT’s units SVC (injected reactive strength Q) and series FACT’s devices TCSC (chose capacitive region) are examined in a 6-bus system. Performance factors are described to show validation of SVC and TCSC on extraordinary conditions. It is proven that the SVC is better than TCSC. </span></p>

The debate over green ICT has been triggered by media during the climate change summit in Kyoto in 2007. This was when the industry tried to build up a clean and non-polluting image. While the Copenhagen summit on the environment failed to produce a conclusive decision, it is now clear that its carbon footprint is a remarkable factor in all business decision making. Governments around the world have set up defined programs and targets that companies have to reach. ICT is aimed at achieving reduction in the 2% of CO2 emission levels. The advantage of the positive impact of Green ICT initiatives would be seen in the clear results in management‘s decision making. However, the adoption of green ICT programs gives the opportunity to fully rethink over current business process and develop new solutions. The benefit of environmental friendly companies can also affect the overall performance and deliver measurable results in terms of customer‘s preference, brand value, ROI, not to count the needed change of behaviour at individual and personal level (such as waste disposal). The chapter wants to outline those topics and properly address the issues behind what the author considers as equivalent to the next industrial revolution.

Human Pointing

The detailed and profound understanding of the temporal and spatial organisation of human pointing actions is key to enable developers to build applications that successfully incorporate multimodal human computer interaction. Rather than discussing an ideal detection method for manual pointing we will discuss crucial aspects of pointing actions in time and space to develop the right solution for a particular application. One core element of pointing in the temporal domain is the so called dwell-time, the time span that people remain nearly motionless during pointing at objects to express their intention. We also discuss important findings about the spatial characteristics of the target representation for the pointing gesture.The findings foster better understanding of the role of pointing gestures in combination with other modalities and inform developer with substantial knowledge about the temporal-spatial organisation of the pointing gesture.

A nation’s economic growth has been associated with the role of entrepreneurship. While recognising the work of entrepreneurship on the mindset and behaviour of individual entrepreneurs, research into an organisational perspective of entrepreneurship continues to emerge due to unprecedented developments occurring around the world over the last two decades. Notably, past studies have postulated that entrepreneurial organisations tend to perform better than conservative organisations. In this vein, the Malaysian government has set up Government-linked companies (GLCs) to enable these entities to become more effective, efficient, and competitive, which can assist the government in strengthening its economy. On the other hand, despite considerable improvements, the overall performance of GLCs has been unsatisfactory. Given the hostility and dynamism of the business environment, GLCs have no other option but to improve and perform better. Recognising this, the purpose of the study is to determine the underlying forces forcing GLCs to improve and to identify forms of corporate entrepreneurship (CE) pursued by GLCs. Building on the outcomes of semi-structured interviews with senior managers in GLCs, the need for CE is fostered by competition and market pressure, technological changes, and increases in operation costs. Finally, future studies of CE in Malaysia may consider other aspects of CE, including issues and challenges in pursuing CE effectively within GLCs business environment.

The thermal Charcoal for domestic used was crushed into powder and mixed with gravel. Four reactors of different proportion and size of charcoal and gravel were set up without vegetation. Sample of landfill leachates obtained from site of Pulau Burung Landfill, Penang, was introduced into the reactors. Ammonia, chemical oxygen demand (COD), and iron of inlet and outlet from four reactors were analyzed by standard methods. Result shows that overall performance of removing ammonia and iron were much better than COD.   Keywords: charcoal, leachate, filter media

✓Brain–computer interface (BCI) technology can offer individuals with severe motor disabilities greater independence and a higher quality of life. The BCI systems take recorded brain signals and translate them into real-time actions, for improved communication, movement, or perception. Four patient participants with a clinical need for intracranial electrocorticography (ECoG) participated in this study. The participants were trained over multiple sessions to use motor and/or auditory imagery to modulate their brain signals in order to control the movement of a computer cursor. Participants with electrodes over motor and/or sensory areas were able to achieve cursor control over 2 to 7 days of training. These findings indicate that sensory and other brain areas not previously considered ideal for ECoG-based control can provide additional channels of control that may be useful for a motor BCI.
