Reconstruction of 3D faces by shape estimation and texture interpolation
This paper aims to address the ill-posed problem of reconstructing 3D faces from single 2D face images. An
extended Tikhonov regularization method is connected with the standard 3D morphable model in order to
reconstruct the 3D face shapes from a small set of 2D facial points. Further, by interpolating the input 2D
texture with the model texture and warping the interpolated texture to the reconstructed face shapes, 3D face
reconstruction is achieved. For the texture warping, the 2D face deformation has been learned from the model
texture using a set of facial landmarks. Our experimental results justify the robustness of the proposed approach
with respect to the reconstruction of realistic 3D face shapes
Hydrothermal hydrolysis of starch with CO2 and detoxification of the hydrolysates with activated carbon for bio-hydrogen fermentation.
The imminent use of hydrogen as an energy vector establishes the need for sustainable production technologies based on renewable resources. Starch is an abundant renewable resource suitable for bio-hydrogen generation. It was hypothesised that starch hydrolysates from a large (250 mL) hydrothermal reactor could support bioH2 fermentation without inhibition by toxic byproducts.\ud

Starch was hydrolysed at high concentrations (40 200 g.L-1) in hot compressed water (HCW) with CO2 at 30 bar in a 250 mL reactor, the largest so far for polysaccharide hydrolysis, at 180 235 °C, 15 min. Hydrolysates were detoxified with activated carbon (AC) and tested in biohydrogen fermentations. The maximum yield of glucose was 548 g.kg starch 1 carbon at 200 °C. 5 hydroxymethyl furfural, the main fermentation inhibitor, was removed by AC to support 70% more hydrogen production than the untreated hydrolysates. The potential utilization of starch hydrolysates from HCW treatment for upscaled fermentations is promising
Friction and wear response of vegetable oils and their blends with mineral engine oil in a reciprocating sliding contact at severe contact conditions
Although many studies investigating the tribological performance of pure vegetable oils have been conducted, a
better understanding of vegetable oil tribological performance at extreme conditions is still needed. Similarly,
little work has been carried out to study the influence of the vegetable oils on the performance of a lubricant
formed from a blend of vegetable oil and conventional mineral engine oil. This work presents the tribological
performance of vegetable oils, and their blends with mineral oil, in a high temperature and contact pressure
reciprocating contact. Palm and soybean based vegetable oils were mixed with a commercial mineral engine oil
at a 1:1 ratio by volume. The conventional mineral oil was also tested to provide a benchmark. The pure palm
oil exhibited lower friction than soybean oil, but for wear performance, this was reversed. The friction
performance of the palm oil was competitive to that of the mineral engine oil. The mineral engine oil was far
superior in wear resistance over both vegetable oils. When blended with mineral engine oil both vegetable oils
demonstrated a reduction in coefficient of friction when compared to their pure oil states. An improvement in
wear performance was observed for both a blend of palm oil and mineral engine oil (25% improvement) and
that of soybean and mineral engine oil (27% improvement). This work shows that for palm oil and soybean oil,
the performance of a blended oil is influenced by its vegetable oil component and that tribological
characteristics of vegetable oils are dominant. That said, the significant limitation of these vegetable oils is their
ability to provide a satisfactory level of wear resistance. It is suggested that any future work in this area should
have a greater emphasis on the enhancement of wear resistance

Modul Psikospiritual-Mangsa Banjir (MPS-MB) serta-merta dan separuh penggal (MID-TERM) pasca banjir
Penerokaan mengenai aspek psikologi mangsa banjir dan keperluan pembentukan modul psikologi dilihat sebagai keperluan penting selepas berlaku bencana banjir besar. Kajian ini dijalankan untuk membentuk Modul PsikoSpiritual-Mangsa Banjir (MPS-MB) yang bakal digunapakai oleh mangsa banjir di negeri Sabah dan Sarawak serta di Semenanjung Malaysia. Seramai 130 mangsa banjir di Gua Musang dan Manik Urai, Kelantan dan Kuching, Sarawak dijadikan sebagai responden kajian. Pemilihan berdasarkan senarai mangsa banjir yang berdaftar di pusat pemindahan banjir. Kajian ini menggunakan reka bentuk exploratory sequential design iaitu dimulakan dengan Fasa 1: Kajian kualitatif, Fasa Interim: Proses Pembinaan Modul dan Fasa 2: Kajian kuantitatif iaitu menguji kesahan muka dan kesahan kandungan oleh pakar dalam bidang psikologi bencana. Di samping itu, kumpulan pengkaji turut menguji trauma mangsa banjir dengan menggunakan soal selidik Peritraumatic Dissociative Experiences Questionnaire (PDEQ) dan Peritraumatic Distress Inventory (PDI). Hasil kajian kualitatif menjadi asas dan panduan kepada pembinaan MPS-MB yang merangkumi lima (5) unit dan 17 aktiviti. Kesahan muka dan kesahan kandungan MPS-MB seterusnya disemak dan dinilai oleh pakar dalam bidang psikologi. Pembentukan MPS-MB mampu menjana ilmu pengetahuan mengenai pengalaman sebenar mangsa banjir berkaitan aspek psikologi dan spiritual. Hasil kajian dan pembentukan modul ini juga membolehkan masyarakat khususnya mangsa banjir mengetahui persediaan masa hadapan agar dapat mengurus dan mengurangkan impak psikologi yang negatif ke atas mangsa bencana banjir

Analisis Rantai Pasok Produk Beras dari Kabupaten Konawe Selatan ke Kota Kendari
This study aims to find out how the supply chain of rice from South Konawe to Kendari. This type of research is included in descriptive research or categorized in qualitative research method by using survey method that is described, explain and interpret a phenomenon that occurs on an object and data is qualitative, ie data that is described with words or sentences by category to obtain a conclusion. This research was conducted in South Konawe Village specifically at UD. Fandi in Laeya District, South Konawe District in August 2017. Data collection techniques were conducted through observation, interviews, discussions with supply chain members and documentation at the research sites. Supply Chain of rice products from South Konawe District to Kendari City starts from Farmers, Rice Millers, Distributors UD Fandi, Retailer and Final Consumer. Farmers as rice suppliers cultivate and sell their crops to the rice mills, then the mills' process rice from farmers into rice products to be sold to Distributor. In this research, the Distributor Party also as the owner of rice milling, after the packaging of rice products, will then be distributed to retailers both in South Konawe District itself and outside the region, especially Kendari City distributor of UD. Fandi has a rice warehouse which is a shelter of rice products that will be sold to retailers in Kendari City. The selling price of rice products from Distributor UD. Fandi is accepted by retailers in South Konawe and outside Kendari especially divided by size, for rice with size 50 kg sold with price Rp. 420.000, - and for rice with size 25 kg sold with price Rp. 220.000, Furthermore the retailers will repackage the rice products into several sizes that are tailored to the needs of the end consumer is the size of 10 kg, and size 5 kg. for rice with size 10 kg sold with price Rp. 110.000, - and rice with size 5 kg sold with price Rp. 55.000, -. But retailers also sell rice with liter sizes which for liters sold to consumers at a price of Rp. 8,000-8,500, / litres. This is done to adjust to the level of end consumer needs

The objective of this research was to know the effect of dringking the alcohol of the teenagers in Aur Sampuk of Sengah Temila District in Landak Regency. In this reserch the researcher used the qualitative descriptive method. The techniques of data collection were observation, interview and the study of documentation, whereas the tools of data collection were the directive of observation, directive of interview, the notes and the files. The result of this research showed that the healthy of the teenagers as the effects of dringking the alcohol was showed by their thin body, concave and red eyes, black lips, and walking with tottering steps, even they vomited and could not wake up. Theimpact of drinking the alcohol for their spirit were they talked too much about strange and pornographic things, they were easier to be offended and angry, their moods were changeable, they always smoke, they never focused and sometimes they hold their heads. Dringking alcohol also gave the bad impacts to the safety of society, such as making the noise till the midnight, playing the loud music, screaming, singing with loud voice, stealing and caused the contention
