Persepsi pelajar tentang keberkesanan aktiviti pengajaran dan pembelajaran dalam amali kejuruteraan elektrik
Kajian ini dijalankan untuk mengenalpasti persepsi pelajar terhadap amali
kejuruteraan yang diamalkan di politeknik bagi subjek Praktikal Kejuruteraan Modul 1
(El003). Kebanyakkan teori pendidikan hanya menekankan kepada teori pembelajaran
yang formal di dalam bilik daijah. Oleh itu tidak banyak yang kita tabu mengenai aktiviti
pembelajaran pelajar melalui kaedah amali. Borang soal selidik telah digunakan sebagai
instrumen untuk mengetahui persepsi pelajar tentang perlaksanaan amali kejuruteraan
bagi subjek ini. Seramai 119 orang pelajar semester satu telah dipilih sebagai responden
kajian. Data telah dianalisis menggunakan perisian SPSS versi 11.0. Analisis statistik
diskriptif telah digunakan untuk menganalisis maklumat yang diperolehi. Hasil kajian
mendapati bahawa tahap kepuasan pelajar untuk aktiviti amali yang disediakan hanya
berada ditahap pertengahan. Pelajar telah menyatakan aktiviti amali yang dijalankan
dapat mencapai objektif pembelajaran dan pensyarah didapati dapat memberikan
penerangan dan penyeliaan yang baik semasa ujikaji dijalankan. Dapatan kajian ini juga
telah menunjukkan bahawa latihan amali yang diberikan dapat membantu pemahaman
teori pelajar tetapi pelajar tidak bersetuju bahawa ujikaji yang disediakan bersesuaian
dengan tahap pemahaman mereka
A Helson matrix with explicit eigenvalue asymptotics
A Helson matrix (also known as a multiplicative Hankel matrix) is an infinite
matrix with entries for . Here the 'th term
depends on the product . We study a self-adjoint Helson matrix for a
particular sequence , , where , and prove that it is compact and that its eigenvalues
obey the asymptotics as ,
with an explicit constant . We also establish some
intermediate results (of an independent interest) which give a connection
between the spectral properties of a Helson matrix and those of its continuous
analogue, which we call the integral Helson operator
Complexity Factor For Anisotropic Source in Non-minimal Coupling Metric Gravity
In this outline we recognize the idea of complexity factor for static
anisotropic self-gravitating source with generalized metric gravity
theory. In present consideration, we express the Einstein field equations,
hydrostatic equilibrium equation, the mass function and physical behavior of
model by using some observational data of well known compact stars like
and . We define the scalar functions
through the orthogonal splitting of the Reimann-Christofell tensor and then
find the vanishing complexity condition for self-gravitating system with the
help of these scalars. It has been found that the vanishing condition for the
complexity are pressure anisotropy and energy density inhomogeneity must cancel
each other. Moreover, we study the momentous results of an astral object for
the vanishing of complexity factor. Finally, these solutions reduced to
previous investigation about complexity factor in General Relativity by taking

A characterization of the Artin-Mumford curve
Let be the Artin-Mumford curve over the finite prime field
with . By a result of Valentini and Madan,
\mbox{Aut}_{\mathbb{F}_p}(\mathcal{M})\cong H with . We prove that if is an algebraic curve of genus
such that \mbox{Aut}_{\mathbb{F}_p}(\mathcal{X}) contains a
subgroup isomorphic to then is birationally equivalent over
to the Artin-Mumford curve
