In organizations, one of the biggest challenges lies in strategic decision-making. In the case of Project Portfolio Management, companies have been incorporating classic tools to reduce uncertainty in this process. This document proposes a new model based on system dynamics, with a different approach to classic strategic project management models. Initially a conceptual model constructed using the root definition of the "Soft System Methodology", proposed by the causal relationships proposed by Peter Chekland and Peter Senge, is proposed. Subsequently, the flow model built on the basis of what is proposed by Jhon Sterman is presented. The model translates the interactions of strategic thinking, project portfolio management, project management and production management into a mathematical model that explains the forms of growth and decline in the real system. It was applied in the Colombian poultry sector in order to validate it. The model is a virtual learning environment that reduces uncertainty in strategic decision-making associated with project portfolios.

Saccharose (SA) and citric acid (CA) were used as additives in P-doped CoMo/Al2O3 catalysts (Mo, Co and P at 12, 3, and 1.6 wt%, respectively) intended to be applied in guaiacol hydrodeoxygenation (HDO). One-pot impregnating solutions were prepared by MoO3 digestion in aqueous H3PO4, followed by C4H6CoO4•4H2O addition. Organics were added (SA/Co=1, CA/Co=2) at two different preparation stages to assess the effect of that step on catalysts properties. Method I: SA or CA was added in as-prepared Co-Mo-P impregnating solution, followed by pore-filling impregnation of alumina support. Method II: SA or CA at aforementioned concentrations was impregnated on the pristine carrier, followed by drying (120 °C, 2 h). Co-Mo-P phases were further deposited on modified supports through corresponding one-pot solutions. All materials were dried (120 °C) but not calcined. Cobalt complexation by CA and Mo-blue LMCT complex formation (SA-modified solids) were identified (UV-vis, oxidic samples). Partially reduced molybdenum (Mo6+ => Mo5+, by XPS) was observed after either organics addition that effect being more evident in SA-modified solids. Materials were gas-phase sulphided (H2S/H2 10%, 400 °C, 2 h) then studied by HR-TEM. Co-Mo-P phases impregnation in one-pot solution simultaneously deposited with SA rendered the materials of the highest MoS2 dispersion.

In the fireworks industry during the bursting of firecrackers, people are affected by health issues by inhaling the chemical particulates matter. When bursting of a firecracker, fuel is mixed with oxygen and releases energy in the form of heat and also contaminated gases. Tamarind seed powder-based fire crackers have been taken for analysis and an emission test was performed. For existing firecrackers, the rate of emissions like CO, CO2, HC, O2, PEF is in the range of 0.032, 0.020, 15, 28.13, and 0.546. For Tamarind seed powder-based firecracker the emission range is reduced compared to the normal firecracker and the emission test results are 0.018, 0.10, 6, 22.12, and 0.546. From the emission test results, the discharge rate of CO and HC, and O2 is reduced for modified firecracker composition. So the Tamarind seed powder-based firecracker influences less emission rate and makes the environment cleaner.

In this paper, we present the design and evaluation of a prototype Autonomous Water Purifier (AWP) for removing heavy metals from contaminated water. The AWP prototype uses solar energy for its operation; the autonomous photovoltaic system is designed to operate up to 8 hours per day and to generate a water flow of 112 liters per day. The prototype was designed to remove biological and chemical agents. It was achieved the elimination of total coliforms, fecal coliforms, total alkalinity, total hardness, total solids, chloride and sulfate from 50 to 100%, as well as the removal of heavy metals. The Pb2+, Hg2+, Cd2+ and Cu2+ were eliminated from 80 to 99%. This wide range of contaminant removal shows a unique way to treat contaminated water in comparison to existing purification systems. The prototype was evaluated with river and spring water from different rural communities of Chiapas, Mexico. The results indicate that the prototype is able to completely remove contaminants in natural waters and get water that meets the guidelines that mark the Mexican official standards. This work helps to solve problems in marginalized communities and natural disaster areas where they have no access to clean water, electricity and suffer from waterborne diseases

A novel Circularly Polarized (CP) Ultra Wideband (UWB) antenna for Ground Penetrating Radar (GPR) applications is presented and discussed in this paper. The proposed antenna is constructed by a question mark shaped radiating patch and a truncated ground plane. A prototype of the designed antenna is fabricated on the FR4-substrate with an overall volume of 0.7λ0×0.793λ0×0.035λ0 at 7 GHz. The simulated results show that the designed antenna has an Impedance Bandwidth (IBW) ranging from 3.14 GHz to 11.88 GHz (116.38%). The CP feature is analyzed and discussed confirming that the antenna maintains a CP radiation characteristic in a broadband with a 3-dB Axial Ratio Bandwidth (ARBW) ranging from 4.13 GHz to 9.28 GHz (76.81%). The measurements were done by utilizing a well calibrated R&S®ZNB Vector Network Analyzer indicating that the fabricated prototype has an IBW nearly ranging from 3.47 GHz to 12.11GHz (110.91%). The results are favorable that ensure the usefulness of this antenna for GPR applications.

This work is focussed at studying the compression ratio (CR) effect on the operating characteristics of a diesel engine fuelled with diesel (80%) and pyrolytic oil (20%) blend, derived from Bael de oiled cake at standard conditions. Engine was operated at three CR’s namely 18:1 (higher), 17.5:1 (standard) and 16:1 (lower). For the blended fuel operation at full load, the brake thermal efficiency (BTE) improved by 5% and brake specific energy consumption (BSEC) diminished by 3% as the CR increased from 17.5 to 18. At high CR, the carbon monoxide (CO) and unburnt hydrocarbon (HC) were lowered by 58.3% and 38.5% respectively for blended fuel when compared to diesel at peak load. The nitrogen oxides emission (NOx) increased by 25.7% for blended fuel at peak load and CR of 18:1. On the whole the experimental results suggest that optimum performance of the engine can be attained at CR 18:1.

Data is a fundamental part of information and management systems; thus, controlling its complexity is an essential step nowadays. NoSQL databases adopt new approaches to data management differing from relational structures. For this study, two database systems are considered, MongoDB as a NoSQL data storage model and PostgreSQL as a relational data model, they are compared and evaluated on a job search system. For this purpose, a dataset was defined, and its representation was constructed in databases based on each technology. This process allowed the data modeling in terms of the best practices, then, the development of a test plan prepared the environment for the determination of the comparison metrics of both databases under the methodology specified by the International Software Testing Qualifications Board (ISTQB) and the types of database testing. This study determined that the SQL schema provides greater functionality, that ensures the support of transactions and data integrity, the opposite happened with the NoSQL schemas, resulting in more efficient but lacking functionalities that are characteristic and required for data representation of a consistent system.

The set partitioning in hierarchical trees is a powerful image compression algorithm. It has reasonable complexity and produces a rate scalable bit-stream. Unfortunately, SPIHT fails to explore the multi-resolution nature of the wavelet transform as the output bit-stream doesn't support resolution scalability. Moreover it requires huge memory and has complex memory management as it depends on utilizing lists with memory of about 2.5 the image size. This paper proposes three related algorithms. The first one modifies SPIHT to reduce its complexity and improve its efficiency especially at low rates. The second is the main contribution of the paper. It provides a simultaneous solution to the memory and scalability problems of SPIHT. Memory is reduced by utilizing status bits of average 2.5 bits per pixel instead of the lists. Resolution scalability is maintained by encoding the resolution levels in increasing order within each coding pass. Another important attribute of our algorithm is that it has very little increment in complexity in comparison with the original SPIHT algorithm. In contrast, the existing solutions have much more complexity, and/or more memory resources. The third has slightly lower complexity and memory than the second but at the same time, it has slightly lower performance.

This paper examines the feasibility of using friction surfacing to deposit Aluminum alloy AA6061 material over an AISI 1017 steel substrate. Further, this work aims to identify the deposition speed settings that would improve the effectiveness of the process. Consumable AA6061-T6 rods were deposited at different combinations of rotational and travel speeds while maintaining the same axial pressing force. The experiment involved 12 speed combinations with 3 replicates from each combination. Quantitative and qualitative methods were used to evaluate speed effects on the overall deposition quality. The evaluation involved different quality indicators including deposition efficiency and stability, surface roughness, deposit hardness and microstructure. Analysis has shown that the rotational speed is the primary factor that significantly affects all of the studied indicators. The travel speed, on the other hand, was found to have significant effects only on deposition efficiency and material hardness.

The key advertisement element “text” has a unique superiority effect on attention and attraction towards advertisements. While a number of studies has examined how an advertisements need to be effective and persuading.
