New Bounds and Constructions for Multiply Constant-Weight Codes

IEEE Transactions on Information Theory, 2016

Multiply constant-weight codes (MCWCs) were introduced recently to improve the reliability of certain physically unclonable function response. In this paper, the bounds of MCWCs and the constructions of optimal MCWCs are studied. Firstly, we derive three different types of upper bounds which improve the Johnson-type bounds given by Chee et al. in some parameters. The asymptotic lower bound of MCWCs is also examined. Then we obtain the asymptotic existence of two classes of optimal MCWCs, which shows that the Johnson-type bounds for MCWCs with distances 2 m i=1 wi − 2 or 2mw − w are asymptotically exact. Finally, we construct a class of optimal MCWCs with total weight four and distance six by establishing the connection between such MCWCs and a new kind of combinatorial structures. As a consequence, the maximum sizes of MCWCs with total weight less than or equal to four are determined almost completely.

Development of cooling load temperature differential values for building envelopes in Thailand

Http Dx Doi Org 10 1080 02533839 2004 9670915, 2011

This article describes the development of cooling load temperature differential (CLTD) values for building envelopes made of materials commonly used in Thailand and using Bangkok weather data. The Bangkok design weather data are selected from 12 years of data collected by the meteorological department. Two sets of weather data for Bangkok are chosen. The first weather data set was selected based on dry bulb temperature of 0.4% annual cumulative frequency of occurrence. The second weather data set was selected based on dry bulb temperature of 0.4% hourly cumulative frequency of occurrence and solar radiation obtained from the ASHRAE mathematical model. The room parameters which have effects on thermal response, such as building envelope material, room decoration, and room conditions are investigated. 288 different room types for each exterior wall type and each roof type were checked. The values of amplitude and delay based on conduction weighting factors for a sinusoidal heat gain are analyzed. The distribution of the amplitude and delay of similar thermal response are grouped together and represented by a single point in the group. For each set of design weather data, 7 CLTD tables for exterior walls and 6 CLTD tables for roofs are developed.

endo-endo-anti Diels-Alder diadduct of hexachlorocyclopentadiene with 1,6-dioxacyclodeca-3,8-diene

Acta crystallographica. Section C, Crystal structure communications, 1998

There are two independent molecules of endo-endo-anti-1,7,8,9,10,16,17,18,19,19,20,20-dodecachloro-4,13- dioxapentacyclo[14.2.1.1(7,10).0(2,15).0(6,11)]icosa-8,17-di ene, C18H12Cl12O2, in the unit cell with different conformations. In one, the ten-membered ring adopts a chair-chair conformation, and in the other, it adopts a distorted chair-chair conformation. There are near-zero torsion angles at the ring-fusion bonds in both forms [1.5 (6) and 8.1 (5) degrees in the chair-chair molecule, and 2.9 (5) and 2.5 (5) degrees in the distorted chair-chair molecule]. The torsion angles about the bonds comprising the sides of the chair-chair are 158.5 (3), -160.7 (3), -146.8 (4) and 155.7 (3) degrees, and those of the distorted chair-chair are 148.0 (3), -146.8 (3), 175.7 (3) and -52.3 (4) degrees. The norbornene C=C bonds have lengths of 1.314 (6) and 1.305 (6) A in the chair-chair molecule, and 1.309 (6) and 1.318 (6) A in the other. The four dioxolane-system O-C bonds have average length...

Population and Human Capital Growth in Egypt: Projections for Governorates to 2051

Human capital formation has been chosen as the initial focal point of this new IIASA population-development-environment case study on Egypt. With its population still likely to double and its water resources severely restricted, Egypt faces formidable population- and environment-related challenges. The government has an explicit population policy aimed at bringing the fertility rate down to replacement level by 2017. With its options for agricultural development severely limited, the future livelihood of this rapidly growing population can only be secured through rapid development in the industrial and service sectors. For both sectors, human capital development is a necessary prerequisite for success. Of course, such development needs to be complemented by the right investment and trade policies. But without a sufficiently well-educated population, Egypt will not be able to compete in the global service and industry markets. The study explores the human capital dimension at the agg...
