In the sector of remote sensing applications, the use of stereo data is on the steady rise. An attempt is hereby made to develop a software suite specifically for exploitation of Cartosat-I data. A few algorithms to enhance the quality of basic Cartosat-I products will be presented. The algorithms heavily exploit the Rational Function Coefficients (RPCs) that are associated with the image. The algorithms include improving the geometric positioning through Bundle Block Adjustment and producing refined RPCs; generating portable stereo views using raw / refined RPCs autonomously; orthorectification and mosaicing; registering a monoscopic image rapidly with a single seed point. The outputs of these modules (including the refined RPCs) are in standard formats for further exploitation in 3rd party software. The design focus has been on minimizing the user-interaction and to customize heavily to suit the Indian context. The core libraries are in C/C<sup>++</sup> and some of the applications come with user-friendly GUI. Further customization to suit a specific workflow is feasible as the requisite photogrammetric tools are in place and are continuously upgraded. The paper discusses the algorithms and the design considerations of developing the tools. The value-added products so produced using these tools will also be presented.

This study investigates to turn the stomach of cow into exotic leather and then leather products that would add value to the end of leather industry. For this purpose, three pieces of cow stomachs are taken to convert into leather through pre-tanning, tanning and post tanning operations i.e. soaking, liming, deliming, bating, pickling, tanning, retanning, dyeing, fatliquoring, finishing etc. Some mechanical operations are also carried out, such as drying and stacking. Several mechanical investigations have been conducted, including tensile strength, stitch tear strength colour rub fastness and shrinkage temperature in order to assess the overall physical properties of prepared leather. Chemical analyses have also been carried out (chromic oxide content, fat content and pH) to find out the quality of leather. It is observed that tensile and stitch tear strengths are much lower than any of the grained upper leather. But the results demonstrate that colour rub fastness is good enough to meet the standard value. Among the different chemical analyses, pH and % of fat content meet the standard value, but chromic oxide content (%) of one sample is below than the standard value of grained upper leather. All these might be due to the prevalence of difference in composition between hide/skin and the stomach of animals. The prepared stomach leather could be used in making of fancy leather goods like key ring, wrist watch belt, hair clip, bracelet etc.

The level of silvicultural investment and area of forest land managed in Canada is rising dramatically. Although this will increase growth rates and help maintain the present level of harvest, it may well result in a reduction in the quality of the resource. The present paper illustrates the risk of ignoring this potential problem through examples of experience in utilizing plantation-grown trees in various parts of the world. Relying on technology to solve all resource quality problems may not necessarily make economic sense. Canada's future must lie in the production of "value-added" products that require a high quality resource, permitting the greatest flexibility in conversion options. Information relating silvicultural treatments to end-product quality is at present inadequate. Large integrated studies addressing these questions and the economics of silvicultural investments in terms of end-product value must be initiated for species that will be managed intensively. With relatively long rotations, Canada cannot afford to create a resource that does not match its future marketing strategy.

This paper presents a user-friendly application developed for assessing the quality of the meteorological forecasts issued by the Moldavian State Hydrometeorological Service (SHS). The scores are calculated using a method developed at Meteo Romania (National Meteorological Administration), which has been running operationally since 1996. The meteorological elements evaluated in this verification system are cloud cover, wind speed, fog, glazed frost, hail, frost, minimum and maximum air temperature, as well as the appearance, shape, distribution and intensity of precipitation. The automatic weather forecasting verification system is based on two graphical interfaces, both of them having a specific role in simplifying the user interaction with the database where the information is stored. This work was realized within the World Bank project "Development of a standardized verification mechanism and QMS for the Moldova SHS".

Aquaculture is growing ever more important due to the decrease in natural marine resources and increase inworldwide demand. To avoid losses due to aging and abnormalweather, it is important to predict seawater temperature in order to maintain a more stable supply, particularly for high value added products, such as pearls and scallops. The increase in species extinction is a prominent societal issue. Furthermore, in order to maintain a stable quality of farmed fishery, water temperature should be measured daily and farming methods altered according to seasonal stresses. In this paper, we propose an algorithm to estimate seawater temperature in marine aquaculture by combining seawater temperature data and actual weather data.

Oat husks are low-value lignocellulosic residues of oat processing that carry an environmental impact. Their polymers (cellulose, hemicellulose, and lignin) can be converted into a wide variety of value-added products; however, efficient pretreatment methods are needed that allow their fine separation for further tailored valorization. This study pioneered the use of milling-free and low acid-catalyzed ethanol organosolv for the delignification of oat husks, allowing their conversion into three high-quality streams, namely, glucan-rich, lignin-rich, and hemicellulosic compound-rich streams. Temperature, retention time, and solid-to-liquid ratio were found to impact the delignification of oat husks when using a one-factor-at-a-time strategy. The ideal conditions that were found (210 °C, 90 min, and solid-to-liquid ratio of 1:2) culminated into glucan and lignin fractions containing 74.5% ± 11.4% glucan and 74.9% ± 7.6% lignin, respectively. These high-purity lignin fractions open the possibility for higher value applications by lignin, potentially impacting the feasibility of second generation biorefineries. The glucan fraction showed 90% digestibility after 48 h of hydrolysis with 10 filter paper units of enzyme cocktail per gram of glucan. Considering the absence of size reduction and high solid loading, together with the quality of the obtained streams, organosolv pretreatment could be a potential strategy for the valorization of oat lignocellulosic residues.

Remote Sensing Applications

Quality assessment of stitched images is an important element of many virtual reality and remote sensing applications where the panoramic images may be used as a background as well as for navigation purposes. The quality of stitched images may be decreased by several factors, including geometric distortions, ghosting, blurring, and color distortions. Nevertheless, the specificity of such distortions is different than those typical for general-purpose image quality assessment. Therefore, the necessity of the development of new objective image quality metrics for such type of emerging applications becomes obvious. The method proposed in the paper is based on the combination of features used in some recently proposed metrics with the results of the local and global image entropy analysis. The results obtained applying the proposed combined metric have been verified using the ISIQA database, containing 264 stitched images of 26 scenes together with the respective subjective Mean Opinion Scores, leading to a significant increase of its correlation with subjective evaluation results.

Terrestrial photogrammetry nowadays offers a reasonably cheap, intuitive and effective approach to 3D-modelling. However, the important choice, which sensor and which software to use is not straight forward and needs consideration as the choice will have effects on the resulting 3D point cloud and its derivatives. <br><br> We compare five different sensors as well as four different state-of-the-art software packages for a single application, the modelling of a vegetated rock face. The five sensors represent different resolutions, sensor sizes and price segments of the cameras. The software packages used are: (1) Agisoft PhotoScan Pro (1.16), (2) Pix4D (2.0.89), (3) a combination of Visual SFM (V0.5.22) and SURE (1.2.0.286), and (4) MicMac (1.0). We took photos of a vegetated rock face from identical positions with all sensors. Then we compared the results of the different software packages regarding the ease of the workflow, visual appeal, similarity and quality of the point cloud. <br><br> While PhotoScan and Pix4D offer the user-friendliest workflows, they are also “black-box” programmes giving only little insight into their processing. Unsatisfying results may only be changed by modifying settings within a module. The combined workflow of Visual SFM, SURE and CloudCompare is just as simple but requires more user interaction. MicMac turned out to be the most challenging software as it is less user-friendly. However, MicMac offers the most possibilities to influence the processing workflow. The resulting point-clouds of PhotoScan and MicMac are the most appealing.

Pyrolysis is one of the effective ways to convert biomass into energy and value added products. Till date, no comparative study has been done on the characteristic of bio-oils of oil palm shell (OPS) and empty fruit bunch (EFB) from various fast pyrolysis techniques. This includes fluidized bed, fixed bed, rotating cone, microwave and others. Thus, the main objective of this paper was to analyze the characteristics of OPS and EFB bio-oils obtained from these processing techniques. Temperature was found to be the key parameter for the quality of bio-oils. Besides the various pyrolysis techniques, the lignocellulosic constituents of oil palm biomass also influence the chemical composition of the bio-oils. Overall, chemical analysis of OPS and EFB bio-oil through GC-MS has shown variation in the amount of phenol and its derivatives.

An experimental study was conducted on the utilization of lamp shell locally known as ugpan to determine the value added products from it. The species of ugpan used was Lingula unguis and was collected in the coastal zone of Nabuswang, Canmoros, Binalbagan, Negros Occidental. Ugpan was tested as raw material into value added products. The meat was utilized into ugpan nuggets and the pedicle was used into crispy ugpan. The liking of ugpan nuggets and crispy ugpan were determined using sensory evaluation. The acceptability of the quality attributes of the value added product was determined using the 9-point hedonic scale. The liking of crispy ugpan showed 80 and 90 for the ugpan nuggets. The acceptability of crispy ugpan had a mean of 8.33 which meant like very much or very much acceptable, while the ugpan nuggets had a mean of 8.0 which meant like very much. The overall quality had a mean score of higher than 8 which means that the ugpan can be utilized into value added products. Improving the quality of ugpan nuggets can increase the hedonic score for the acceptance of the product. The result of this study will served as the extension project of the institution.   Keywords - Technology, crispy ugpan, Lingula unguis, quality, ugpan nuggets, Negros Occidental, Philippines
