Bukit Choras Archaeological Complex: Geophysical And Geo-Archaeological Analysis

Ancient Kedah is a collection of several riverine and coastal settlements which flourished as the foci for international trade and industry between the 2nd to the 14th Century C.E. The Bukit Choras Archaeological Complex is one of the very few well-preserved archaeological findings related to the cultural and economic development of Ancient Kedah. Previous studies had revealed two structural remains made of laterite bricks, two ancient water tanks, as well as other artefacts such as potsherds, Buddhist inscription and corroded iron nails. This research attempts to answer questions regarding the layout, building material and palaeo-environment of the site. In this study, geophysical studies were carried out in Bukit Choras in order to map the surface remains and to determine the potential for buried remains. Detailed contour mapping as well as the magnetic, resistivity and ground penetrating radar methods were done around the main structure and the ancient water tank

Koleksi tembikar tradisional di Muzium Negeri Kelantan, Kota Bharu: satu penelitian awal terhadap reka bentuk dan corak

Makalah ini membincangkan tentang hasil penelitian awal yang dijalankan terhadap koleksi tembikar tradisional yang terdapat di Muzium Negeri Kelantan (MNK), Kota Bharu, Kelantan. Tujuan kajian ini dijalankan adalah untuk mendokumentasikan jenis, bentuk dan ragam hias tembikar Mambong menggunakan kaedah analisis morfologi. Turut dianalisis dalam kajian ini adalah Kelantan. Antara ciri-ciri morfologi penting yang dianalisis dan direkodkan dalam kajian ini adalah ukuran tinggi, panjang, ukur keliling, bukaan mulut dan corak pada bahagian penutup, bibir, leher dan badan tembikar. Hasil penelitian mendapati terdapat lapan (8) jenis tembikar Mambong yang dihiasi dengan empat (4) jenis motif hiasan utama iaitu flora, fauna, elemen kosmos dan geometri. Setiap ragam hias ini boleh dibahagikan kepada beberapa sub-corak. Sebaliknya, tembikar tradisional dari Kampung Periok terdiri daripada satu jenis tembikar sahaja dan dihiasi dengan corak yang hampir sama dengan tembikar Mambong. Secara keseluruhannya, makalah ini telah menyumbang data dan maklumat baharu tentang koleksi tembikar tradisional yang terdapat di MNK, Kota Bharu, Kelantan. Hasil penelitian ini boleh dijadikan sebagai bahan rujukan ilmiah oleh penyelidik, pelajar dan komuniti yang berminat untuk mengenali seni dan budaya tembikar tradisional di Kelantan khususnya dari segi jenis tembikar, reka bentuk tembikar dan ragam hias tembikar

Koleksi tembikar tradisional dan tembikar prasejarah di Muzium Sultan Abu Bakar, Pahang: dokumentasi dan analisis morfologi awalan

Artikel ini melaporkan hasil kerja dokumentasi dan analisis tembikar yang telah dijalankan di Muzium Sultan Abu Bakar, Pekan, Pahang. Sebanyak lapan belas (18) tembikar tradisional iaitu dua belas (12) daripadanya ialah tembikar jenis terenang, lima (5) jenis belanga dan satu (1) tembikar jenis periuk serta beberapa serpihan tembikar prasejarah telah direkodkan. Kesemua tembikar ini telah dikaji menggunakan pendekatan morfologi. Analisis morfologi adalah satu bentuk kajian tentang ciri fizikal tembikar seperti saiz, berat, warna, bentuk, ketebalan, kemasan permukaan dan hiasan. Kajian-kajian lalu turut membuktikan bahawa nilai estetika pada tembikar dapat dijelaskan melalui bentuk motif, simbol dan ragam hiasnya. Analisis morfologi yang dijalankan ke atas tembikar prasejarah juga telah menyumbang maklumat asas tentang profil bibir dan ragam hias tembikar dari tiga buah tapak arkeologi di Pahang iaitu Gunung Senyum, Gua Bama dan Gua Sagu. Laporan awal ini diharapkan dapat menjadi bahan rujukan asas bagi kajian tembikar di Muzium Sultan Abu Bakar pada masa akan datang sekali gus memperkasa pengetahuan kita tentang warisan tembikar dulu dan kini di Pahang

Computerized conductometric determination of stability constants of complexes of crown ethers with alkali metal salts and with neutral molecules in polar solvents

A computerized conductometric procedure for the determination of stability constants of the complexes of crown ethers (15-crown-5, benzo-15-crown-5 and 12-crown-4) with alkali metal salts in polar solvents is described, based on a microcomputer-controlled titration system. For the control of the experiments from software, a modular computer program was written in FORTH computer language. The procedure is especially suitable for the study of 1:2 metal ion/ligand complexes, which occur frequently with the compounds used. For the study of the interaction between crown ethers and neutral molecules, an indirect procedure is outlined

On studying the effect of information warfare on C2 decision making

The goal of practitioners of information warfare is always concerned with affecting the decisions made by the enemy. With a clear understanding of how the enemy makes decisions, it is easier to target the processes which are involved in making those decisions. The purpose of this thesis is to demonstrate whether information warfare, when directed at a command and control decision maker, can be administered in quantified amounts which can be used to change what would normally be a good tactical decision into a bad one. This thesis uses a software package called Tactical Tic-Tac-Toe (T4), to simulate command and control decisions being made in an information warfare environment. The three measures of effectiveness of winning battles, winning missions (aggregate battles), and increasing one's won-to-loss ratio are used to evaluate the quality of the decisions being made. Fog of War, Tactical Delay, Area Delay, and Communications Delays are combined to determine their effects on command and control under these measures of effectiveness. Clearly the data shows that delaying one's immediate opponent from grasping the tactical picture serves to greatly enhance the chances of increasing one's effectiveness. Further, delaying the enemy's understanding of 'pieces' of the strategic picture (which might not be viewed as immediately tactically important), also dramatically increases effectiveness.http://archive.org/details/onstudyingeffect1094530847NANAU.S. Air Force (U.S.A.F.) author

Reduction techniques for the persistent homology transform on digital images

Giusti, ChadA digital image can be naturally represented as a set of lattice cubes defined by elementary intervals. This thesis presents a new object to represent digital images, the generalized cubical complex. This combinatorial object is also composed of lattice cubes, but does not restrict its cubes to be defined by elementary length intervals. The union of these cubes represents a space in R^n. We later show how to construct a generalized cubical complex’s persistent homology transform (PHT) and prove two generalized cubical complexes representing the same space in Rn have the same PHT. Using image segmentation, we show a digital image can be represented by an object requiring less information with respect to its traditional representation which retains its PHT.University of Delaware, Department of Mathematical SciencesM.S
