A systematic experimental investigation to understand the effect of heat loss and the thermoelectric aspect ratio (cross sectional area and length) on a flat plate solar thermoelectric system performance was carried out. The investigation involved a series of experiments on systems with 4 different sizes of thermoelectric generators, and it was tested in 5 different vacuum levels during the steady-state. The detailed experimental investigation provided a substantial amount of data, which revealed that the system performance of both heat and electricity power were improved when the heat lost was minimised. The system’s performance strongly depended on the aspect ratio of the thermoelectric generators. This finding might have a significant impact on the cost of the system by saving the user’s and the manufacturer’s time in examining different TEGs with different aspect ratios in order to get the optimum size optimisation of the hybrid system, as well as reduce the manufacturing cost.
is a human and context oriented study in the field of information systems (IS),
human resource information systems (HRIS), leadership, human resource
management (HRM) and tacit knowledge are focused in the study. HRIS and
leadership are two main concepts of the research, whereas HRM provides an
application area and managerial activities of leadership for HRIS. Tacit
knowledge is used to describe and interpret actions that make leadership activities,
sensitive and successful. The theoretical framework consists of when thinking
and acting in the current way, what kind of information systems it produces,
and when thinking and acting in another way, what kind of information systems
it creates. The framework has its base on thinking and acting in a
conventional, routine and stereotyped way, which hinders the process of
observing, finding out, applying and using alternative thoughts and actions
although they might provide useful and innovative solutions or activities for
IS design. The main idea is to understand, interpret and to describe the
phenomenon of the activities of good leadership and the phenomenon of the role
of HRIS in the case organizations.
A decomposition of a graph H is a partition of the edge set of H into edge-disjoint subgraphs . If for all , then G is a decomposition of H by G.
Two decompositions and of the complete
bipartite graph are orthogonal if, for all . A set of decompositions of is a set of k mutually orthogonal graph squares (MOGS) if and are orthogonal for all and . For any bipartite graph G with n edges, denotes the maximum number k in a largest possible set of MOGS of by G. Our objective in this
paper is to compute where is a path of length d with
