Data collection is one of the most relevant topics of modern automation and industry. It is usually a costly and time-consuming task, especially in continuous processes. Our case study takes place in a sugar cane mill. The required continuous operation of a belt conveyor for bagasse transportation makes it a critical system in the overall production process. Therefore, a predictive maintenance tool is highly applicable here. We identified bearing housings as critical points for data collection intended for prognostics of the conveyor. However, given the number of points, the cost of a commercial solution becomes unfeasible by our company. This paper reports the development of low-cost devices for measurements and wireless transmission of vibration and temperature data from bearing housings. We assessed several sensor options and made decisions based on a cost-suitability commitment, which led to the design of the electronic devices. The devices were tested for correct operation, reliability (99%), and relative measurement errors under 1.2%. From the tests, we conclude that our proposal is appropriate for our case study’s industrial needs and budget restrictions.

AbstractLakes, rivers, estuaries and ocean waters control many important natural functions at the regional-global level. Hence, integrative and frequent long-term water monitoring is required globally. This paper describes the main features and innovations of a low-cost monitoring buoys network (MBN) deployed in a temperate region of Argentina. The MBN was designed to record extended time series at high-frequency, which is of great value for the scientific community, as well as for decision-makers. In addition, two innovative designs belonging to two versions of moored buoys (i.e. shallow waters and coastal marine waters) were presented. It was shown that the cost of either of two versions of the buoy is low, which can be considered as the main advantage.

The authors report their experience from various task analysis projects in which users have been observed in situ. Solutions for simultaneous video recording, often needed to adequately observe and analyze a workspace, are discussed. Of the various analog- and digital-based solutions, the authors deem a low-cost solution using entry-level computer hardware to produce sufficiently high-fidelity feedback for most task analysis purposes. Such systems can be acquired and set up by novice computer users for a fraction of the cost of broadcast video systems. A case study demonstrates the application of one such inexpensive solution.

Recent studies on textbook costs in the United States have indicated that there is a direct relationship between textbook costs and student success. With textbook costs increasing at a rate higher than the cost of living, many students have cited the textbook cost as an extremely important factor when obtaining (or not obtaining) a textbook. Open educational resources (OER) are tools that educators can use to supplement or build a course. OER are free for anyone to reuse, revise, remix, and redistribute and are a low-cost, tailored solution for faculty and students. There have been calls for research that demonstrates how OER are being put into practice. This case study examines the responses of users to a voluntary survey in a capstone business course that implemented OER in lieu of traditional textbooks. The study suggests that, for teachers and students, as well as self-directed learners, OER provide a valuable resource to eliminate the pay wall, improve learning design, and support the power of the community through sharing and collaboration.

Abstract Groundwater is one of the most important water sources but it is often not far away from pollution. One source of pollution is leakage from polluted streams such as open drains. The effect of open drains on groundwater quality has become an essential issue. This study aims to use different lining materials to minimize the seepage from open drains to protect groundwater. MODFLOW is used to investigate flow and contaminant transport and to evaluate efficiency of different lining materials. A hypothetical case study is used to assess different lining materials such as clay, bentonite, geomembranes and concrete. The results showed that decreasing the conductivities of lining materials reduced the extension of the contaminate. The extension of contaminants was reduced by 43, 89.6, 91.4 and 93% compared with the base case when drains were lined by clay, bentonite, geomembranes and concrete, respectively. Also, cost analysis of lining materials was done to detect the best lining material. Lining using geomembranes reduced contaminant extension at low cost compared with concrete, which reduced contaminant extension at double the cost. This reveals that the geomembranes represent the preferred material to protect groundwater from drain seepage due to its high durability and low cost compared with concrete.

Biofuels are still too costly to compete in the energy market and it has been suggested that low-value feedstocks could provide an opportunity for the production of low-cost biofuels; however, the lower quality of these feedstocks requires the introduction of a conditioning step in the biorefinery process. The aim of this study was to evaluate whether feedstock savings cover the cost of conditioning in the case of animal bedding. The BioSTEAM software was used to simulate a wheat straw biorefinery and an animal bedding biorefinery, whose economic performance was compared. The wheat straw biorefinery could deliver ethanol at a minimum selling price of USD 0.61 per liter, which is similar to prices in the literature. The cost of producing ethanol in the animal bedding biorefinery without water recycling was almost 40% higher, increasing the minimum selling price to USD 1.1 per liter of ethanol. After introducing water recycling in the conditioning step, the animal bedding biorefinery could deliver ethanol at a minimum selling price of USD 0.38 per liter, which is 40% lower than in the case of the wheat straw biorefinery. This demonstrates that low-value feedstocks can be used to reduce the biofuel price, as feedstock savings easily cover the additional conditioning cost.

Costing is an important issue in a competitive world. Many companies had adopted TDABC for better cost visibility. Assembly is very common activity in the small scale industries (SSI). In a SSI, many operations like riveting, drilling, fastening, loosening and tightening, hammering, labeling, aligning, etc. are carried out at the time of assembly. Also the sequence and the time of the operating vary for each product. Therefore, it is difficult to estimate the cost of complex assembly. This paper proposed a time driven activity based costing (TDABC) model to estimate the cost of assembly for SSI. TDABC uses time equations to estimate the time required for an activity. A new approach to develop the time equation using maynard operation sequence technique (MOST) is presented. This paper also presents the modification in the time equation to handle the complexity of the activity. The application of the model is presented with the case study. The cost analysis helps to identify the opportunities for low cost assembly solution.

Abstract Disposal of plastic waste is a serious problem, because plastics accumulate in the environment and cause significant pollution due to their degradability. Therefore, the main objective of this research was to reach the biodegradable plastics industry as alternatives to non-biodegradable plastics. And the existence of such biodegradable plastic must contribute in reducing the emission of harmful greenhouse gases and keeps the environment clean, and reduces the cost for pollution from the accumulation of plastic waste. Algae was used as a raw material for the production of bio-plastics because of its unique properties such as it grows rapidly and in large quantities at a low cost and grows in a variety of water environments throughout the year, which means that there is no risk in the difficulty of securing the raw materials needed for the production of bio-plastics The study concluded that the tested samples partially decomposed in fresh and alkaline water during a period of 26 days, which means a high dependence on algae to the production of bio plastics as an environmentally friendly industry.
