Important criteria for measuring heritage building condition
No full textThe excellence condition of a heritage building lies not only in the appearance of its individual elements, but also in the integrity of all its components, considered as unique criteria of the specific construction technology of its time and place. However, these criteria are varied and not specific. Therefore, this study aimed to identify and rank the important criteria for measuring the condition of heritage buildings in Malaysia. Data obtained through questionnaire and analyzed using Average Index (AI) in order to establish the important criteria. Samples were selected from a panel of experts in the field of heritage buildings management including industry players and academicians. The established criteria will be used as components to develop a new method of heritage building condition determination model in Malaysia
A measurement of the Q(2), W and t dependences of deeply virtual Compton scattering at HERA
No full textDeeply virtual Compton scattering, γ*p→γp has been measured in e+p collisions at HERA with the ZEUS detector using an integrated luminosity of 61.1 pb-1. Cross sections are presented as a function of the photon virtuality, Q2, and photon-proton centre-of-mass energy, W, for a wide region of the phase space, Q2 > 1.5GeV2 and 40 < W < 170GeV. A subsample of events in which the scattered proton is measured in the leading proton spectrometer, corresponding to an integrated luminosity of 31.3 pb-1, is used for the first direct measurement of the differential cross section as a function of t, where t is the square of the four-momentum transfer at the proton vertex. © SISSA 2009

Search for a W' boson decaying to a vector-like quark and a top or bottom quark in the all-jets final state at 1as=13 TeV
No full textAbstract: A search is presented for a heavy W' boson resonance decaying to a B or T vector-like quark and a t or a b quark, respectively. The analysis is performed using protonproton collisions collected with the CMS detector at the LHC. The data correspond to an integrated luminosity of 138 fb(-1) at a center-of-mass energy of 13 TeV. Both decay channels result in a signature with a t quark, a Higgs or Z boson, and a b quark, each produced with a significant Lorentz boost. The all-hadronic decays of the Higgs or Z boson and of the t quark are selected using jet substructure techniques to reduce standard model backgrounds, resulting in a distinct three-jet W boson decay signature. No significant deviation in data with respect to the standard model background prediction is observed. Upper limits are set at 95% confidence level on the product of the W' boson cross section and the final state branching fraction. A W boson with a mass below 3.1 TeV is excluded, given the benchmark model assumption of democratic branching fractions. In addition, limits are set based on generalizations of these assumptions. These are the most sensitive limits to date for this final state
Fara'id in the Pahang State of Malaysia: Theory and practice
No full textThis present study concerns fara'id and its application in Pahang State, Malaysia, from the theoretical and practical aspect. Fara'id is the law concerning intestate
inheritance and is the subjects of the most detailed legal provision revealed in the Quran. Because of its importance the Prophet urged his companions to acquire this particular knowledge and warn them that `ilm al-Farä'id or the science of estate distribution is the first knowledge that will be taken away from his ummah or society. Since fara'id literally means obligations, many have assumed that it is an obligatory law, which Muslims have no choice but to obey. The study, however, concludes that it
is not an obligation for Muslims to dispose of their inheritance in accordance with the fixed fractional shares prescribed in the Quran, as the rules of fara'id also
acknowledge a form of distribution or settlement based on the concept of mutual agreement, as can be seen in the principle of al-Takharuj.
Practically, the study found that there are two settlement methods applicable in the State of Pahang: fara id and mutual agreement. Nevertheless, the study revealed that the percentage of Muslim cases settled by fara id is much lower than that of those settled by mutual agreement, the main reason for this being that settlement by mutual agreement is much faster than settlement by farä id It was also found that the advice given by the officer in charge also played an important part in influencing the claimants' decision to settle their case by mutual agreement.
An examination of the Muslim cases settled by the authoritative agencies revealed that there are settlements, which are not in accordance with the principles of Islamic
law and fara id in particular. This was due to three factors. Firstly, the acts themselves; secondly, the decisions of the High Court; and thirdly, the mistakes made
out of ignorance by the officer in charge. A study of the cases of Muslim inheritance also revealed that farä'id as applied in the State of Pahang continues to be based on
the traditional law of the Shäf ii school and up to the present day no attempt been made in Malaysia to follow the example of other Muslim countries such as Egypt, Syria, Sudan, Tunisia and Pakistan in reforming the law

A Theoretical Model to Calculate Redshift of Galaxies and Quasi-stellar objects (QSO)
No full textAbstract A simple geometrical model considered to calculate redshift values of 378 celestial objects such as Galaxies and Quasi stellar objects(QSO). In this model, Earth as a small point located in the centre of theoretical observation. This constructed model, is based on the angle of observation from Earth. Although, theoretical and experimental results of this model show a well consistent for some objects, however final verification, need more and accurate data
Sparse reconstruction for integral Fourier holography using dictionary learning method
No full textA simplified (i.e., single shot) method is demonstrated to generate a Fourier hologram from multiple two-dimensional (2D) perspective images (PIs) under low light level imaging conditions. It was shown that the orthographic projection images (OPIs) can be synthesized using PIs and then, following incorporation of corresponding phase values, a digital hologram can be generated. In this work, a fast dictionary learning (DL) technique, known as Sequential Generalised K-means (SGK) algorithm, is used to perform Integral Fourier hologram reconstruction from fewer samples. The SGK method transforms the generated Fourier hologram into its sparse form, which represented it with a linear combination of some basis functions, also known as atoms. These atoms are arranged in the form of a matrix called a dictionary. In this work, the dictionary is updated using an arithmetic average method while the Orthogonal Matching Pursuit algorithm is opted to update the sparse coefficients. It is shown that the proposed DL method provides good hologram quality, (in terms of peak signal-to-noise ratio) even for cases of ~ 90% sparsity.Authors sincerely thank Dr. Ni Chen of Visual Computing Center, King Abdullah University of Science and Technology (KAUST), for providing the integral hologram dataset.
