Abstract: According to the practical application demand of the college dormitory, combined with principle, architecture, and technical of Internet of Things, a college dormitory construction scheme is proposed based on the Internet of Things. The scheme concludes technical framework improvements of the Internet of Things for application, discussion of the networking mechanisms, implementations of technical details and design of network nodes. It presents a multi-frequency-multi-structure network architecture. Test results of typical application parameters show that the practical application of the scheme in a college dormitory is feasible.

What Do University Endowment Managers Worry About?
An Analysis of Alternative Asset Investments and Background Income

Working Paper No. 244, June 2015
Abstract. This paper examines whether university endowment managers think only in terms of the assets they manage, or also take into account background income, the other flows of income to the university. Specifically, we test whether the level and variability of a university’s background income (e.g., from tuition and government grants) affect its endowment’s allocations to so-called alternative assets such as hedge funds, private equity, and venture capital. We find that both the probability of investing in alternative assets and the proportion of the portfolio invested in such assets increase with expected background income and decrease with its variability

Lightning protection techniques for roof-top PV systems
Narjes Fallah, et. al
ABSTRACT: In this paper, the lightning protection requirements of a typical residential building have been discussed and techniques have been provided to protect the building from both direct and indirect damages of lightning, with special attention to the protection of PV panels placed on the roof. These techniques include the designing challenges and also the type of devices which can be used to reduce the surge current flow and magnetic field. It has been shown that for buildings with roof top PV systems only the avoidance of lightning attachment to unprotected parts of the building is not sufficient. Lightning currents passing through the lightning protection system may still affect the PV power system through inductive coupling. Hence strategic placement of PV systems and shielding of conducting systems wherever possible has been recommended. It has also been envisaged that the impact of lightning on PV systems is directly related to the isokeraunic level of the region and elevation of the building. Several recommendations have been proposed in designing the air termination system for a roof with PV panels in high isokeraunic regions. Finally the building integrated photo voltaic (BIPV) projects which are conducted in Malaysia have been evaluated..
