Engineering Applications of Artificial Intelligence

This paper proposes a new concept of thick gradual sets (TGSs), which is based on the notions of thick sets (TSs) and gradual sets (GSs). A TS is an uncertain set, which is represented by a pair of crisp sets (CSs). These CSs represent the upper and lower bounds of the TS. Therefore, a TS can be considered as an interval of CSs. A GS is a CS, which is parameterized by a degree of pertinence and aims to increase the specificity of CSs. Furthermore, a TGS is an interval of GSs, i.e., a pair of lower and upper GSs. In situations when the constraint of monotonicity (consistency) is guaranteed, a GS becomes a type-1 fuzzy set (T1FS) and a TGS can be regarded as a thick fuzzy set (TFS). Moreover, a TFS, which is composed of lower and upper T1FS bounds, can be interpreted as a type-2 fuzzy set (T2FS). According to the TGS representation, this new approach offers an original concept for interpreting, manipulating, and computing some uncertain quantities that cannot be represented by GSs, T1FSs, and/or T2FSs. The potential applications of the TGS concept has been validated using application examples in the frameworks of solving fuzzy systems of equations and uncertain fuzzy regression and through a real-world application where the trajectory of an underwater robot is uncertain and cannot be precisely known because of disturbances induced by the environment. The proposed approach makes it possible to compute the uncertain zone explored by the underwater robot.
The influence of quality factors on Crowdfunding Success

, The research question which is going to be answered in this paper is ‘To what extent is crowdfunding success explained by quality factors? ’ This research is on how crowdfunding success is influenced by the social network of the project leader and the quality of preparation. The social network of the project leader will be tested via their Facebook friends and LinkedIn connections, while the quality of preparation will be tested via the business plan and the business video. This paper uses data extracted from Kickstarter projects. Based on our sample, we conclude that the amount of friends on Facebook has a positive influence on crowdfunding success. However, our data does not suggest a positive effect of the amount of LinkedIn connections on crowdfunding success. Furthermore, based on our sample, we conclude that the quality of preparation positively affects crowdfunding success.
Genome-Wide ChIPseq Analysis of AhR, COUP-TF, and HNF4 Enrichment in TCDD-Treated Mouse Liver

The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor known for mediating the toxicity of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and related compounds. Although the canonical mechanism of AhR activation involves heterodimerization with the aryl hydrocarbon receptor nuclear translocator, other transcriptional regulators that interact with AhR have been identified. Enrichment analysis of motifs in AhR-bound genomic regions implicated co-operation with COUP transcription factor (COUP-TF) and hepatocyte nuclear factor 4 (HNF4). The present study investigated AhR, HNF4α and COUP-TFII genomic binding and effects on gene expression associated with liver-specific function and cell differentiation in response to TCDD. Hepatic ChIPseq data from male C57BL/6 mice at 2 hrs after oral gavage with 30 µg/kg TCDD were integrated with bulk RNA-sequencing (RNAseq) time-course (2 - 72 hrs) and dose-response (0.01 - 30 µg/kg) datasets to assess putative AhR, HNF4α and COUP-TFII interactions associated with differential gene expression. TCDD treatment resulted in the genomic enrichment of 23,701, 11,688, and 9,547 binding regions for AhR, COUP-TFII and HNF4α, respectively, throughout the genome. Functional enrichment analysis of differentially expressed genes (DEGs) identified differential binding enrichment for AhR, COUP-TFII, and HNF4a to regions within liver-specific genes suggesting intersections associated with the loss of liver-specific functions and hepatocyte differentiation. Analysis found that the repression of liver-specific, HNF4α target and hepatocyte differentiation genes, involved increased AhR and HNF4α binding with decreased COUP-TFII binding. Collectively, these results suggested TCDD-elicited loss of liver-specific functions and markers of hepatocyte differentiation involved interactions between AhR, COUP-TFII and HNF4α.
Journal of Applied Animal Nutrition

Limestone is used as the major source of inorganic calcium (Ca) in poultry diets. The influence of limestone particle size and solubility on quality and performance outcome measures has been intensively studied in layers and broilers. Results from studies in layers indicated that large particle size (>1 mm diameter) can improve egg shell quality, Ca retention, bone mineral content and breaking force – effects which are thought to result from an increase in retention time in the gizzard, thus increasing the in vivo solubility and utilisation of Ca in laying hens (Araujo et al., 2011; Cheng and Coon, 1990; Rao et al., 1992; Roland, 1986; Zhang and Coon, 1997). Fewer studies are available for broilers, in which smaller particle size (<1 mm diameter) is commonly used in commercial diets. Guinotte et al. (1991, 1995) reported that large particles of Ca (>0.6 mm diameter) reduced Ca retention and bone mineralisation compared to fine particles of Ca (0.15 mm diameter) in broilers. Anwar et al. (2016, 2017) showed that limestone particle size and solubility had a marked effect on Ca digestibility, which was higher with coarse, less soluble limestone (1-2 mm diameter) than with fine, more soluble limestone (<0.5 mm). This was attributed to a slower Ca-release in the Effect of two commercial limestone sources with different solubility on the efficacy of two phytases in 0-21 d old broilers
Review on approaches of diagnosis of diabetic retinopathy at early stage

The innermost and light-sensitive layer of tissue of the eye is retina. This tissue suffers a disease generally known as Diabetic retinopathy (DR). The disease must be treated at early stage for preventing its growth. The necessity of diagnosing at earlier stage is the main motive of a researcher. The growth of this disease may result in complete sight loss. The developing nations do not have enough skilled ophthalmologists. Moreover, people don’t have enough knowledge of this disorder. The early treatment can be provided to the patients for preventing this disease from growing to further stage.

Life-cycle cost analysis of cracking in a reinforced concrete beam under uniform chloride corrosion

Corrosion of rebar is one of the major problems in reinforced concrete structures under a corrosive environment which causes serious damage to the structures. Corrosion of rebar is a complex process and one of the important factors of failure of reinforced concrete structures which reduces the strength and serviceability of the structures thus avoiding these adverse effects requiring a high cost. For this reason, this process needs to be modeled using probabilistic analysis and reliability analysis with uncertainties in the corrosion phase. Considering the different maintenance strategies and life cycle analysis methods, the cost of maintenance and repair can be delayed. One of the corrosion effects on structure performance is crack on the concrete surface due to the expansion of the corrosion product. The crack width is an important parameter for designing and evaluating the performance of concrete structures. Therefore, this paper presents an analytical model to calculate the crack width due to corrosion. Crack evolution in the concrete cover due to expansive corrosion products is investigated at different stages during crack propagation across the cover, from the reinforcing bar-concrete interface to the concrete. A merit of this model is that it is directly related to the factors that affect the corrosion-induced cracking process. Then, the predicted crack width is chosen as a stochastic variable and the probability of failure in concrete structures is calculated by using a stochastic deterioration model and the gamma process. The calculated probability is then used to calculate the life cycle cost and determine the optimal repair time by using the renewal process. The effect of structural parameters on the probability of failure is also investigated. The results show that the corrosion rate is one of the most important factors affecting the crack width, the probability of failure and life cycle cost.
Hs-CRP as an important inflammatory risk marker of CAD in diabetes mellitus patients

Background: Elevation of hs-CRP is associated with increased risk of type 2 diabetes development in patients with all levels of metabolic syndrome. This study aimed to assess the hs-CRP among the patients with CAD in type 2 diabetes mellitus. Materials and Methods: All the patients admitted under cardiology department of PMSSY Bangalore medical college were included in present case control study, conducted between November 2017 to May 2019. The patients with known history of diabetes mellitus for 5-10yrs of duration and willing to be part of study with age >40 were included in present study. Results: Total 70 patients were included who fulfilled the inclusion criteria. Among them 35 were T2DM with CAD (Group A) and 35 were T2DM without CAD (Group B). Among them 40 were males and 30 were female patients. The mean age of patients was 57.2±9.4 in group A and 58.210. 4 in group B patients, which was statistically not significantly different. There was a significant higher mean hs-CRP in patients of group A compared to group B patients. Conclusion: Hs-CRP is a reliable marker for the atherosclerotic events, and there is a significant relation of coronary artery disease with the elevated hs-CRP in patients. We suggest that patients with diabetes mellitus should undergo a routine screening for hs-CRP levels to detect risk of CAD at early phase. Keywords: Diabetes mellitus, Coronary artery disease, Hs-CRP, Metabolic syndrome.
The Effects of Compost-Derived Dissolved Organic Carbon on Cd, Zn, and Cu Release From Metal-Spiked Soils

Dissolved organic carbon (DOC) can affect the mobility or bioavailability of heavy metals in a soil system. We investigated the effects of two compost-derived DOC solutions on the release of Cd, Zn, and Cu from two metal-spiked agricultural soils via repeated extraction experiments under acidic conditions. The two soils used in this study were acidic (pH 5.1-5.7) and differed primarily in soil texture (Sankengtzu [Sk] sandy loam vs. Potu [Pu] silty clay loam). The soils were spiked with individual metals (Cd, Zn, or Cu) to levels close to the limits imposed by local regulations. The metal-spiked soils were treated with two acidified DOC solutions (10 mmol/L DOC; pH 3; Na+ exchanged), one derived from sewage sludge compost and the other from swine manure compost, followed by repeated extraction experiments. The results showed that the addition of DOC in the extraction solution can accelerate the acidification and the release of Cd, Zn, and Cu from the two soils. This effect was more obvious for the Sk sandy soil than for the Pu clay soil. The two DOC solutions, which were extracted from different sources, showed different behaviors of metal release. The differences might be related to the acid strength, metal-binding strength of acid sites, and the presence of other anions. The release of Cd from the soils was controlled mainly by the pH of the soil. Neither an inhibition effect of chloride ions nor an improvement effect of DOC on the Cd release was found. The release of Zn was slightly inhibited (∼10%) by the DOC solution extracted from the sewage sludge compost (or Neihu secondary sludge compost [NH2SC]-DOC), especially from the Sk sandy soil, which was assumed to be the result of the formation of sulfide. The use of DOC extracted from the swine manure compost (or SMC-DOC) can result in the release of more Cu (up to 35%-40%) from both soils. The DOC solutions can be used for enhancing the efficiency of acid-washing techniques used for metal-contaminated soil remediation (especially for Cu).
Multi-Objective Optimization Design of a Multi-Permanent-Magnet Motor Considering Magnet Characteristic Variation Effects

In this article, a parallel-series magnetic circuit multi-permanent magnet (M-PM) motor is designed and optimized considering magnet characteristic variation effects, where two kinds of permanent magnets (PMs) are utilized as co-magnetic. Based on the equivalent magnetic circuit method, the detailed design method for the M-PM motor is illustrated. Considering the various operation conditions in potential electric vehicle applications, the B–H curves of two PMs of different typical operation conditions are obtained. Then, a multiobjective optimization method is newly proposed which not only focuses on the magnet characteristics variation effect but also considers output torque, torque ripple as well as antidemagnetization capability under three typical operation conditions. The performances of the initial motor and optimal motor are compared under typical operation conditions. Finally, a prototype machine is built and tested. Both theoretical analysis and experimental results verify the validity of the motor and the proposed design optimization method.

Pediatric surgical outreach program can achieve reduction in surgical disease burden of children in the rural areas.
Computer-generated Works under the CDPA 1988

Copyright protection in some commonwealth jurisdictions extends to computer-generated works. Although many scholars deem the right over computer-generated works to be a neighbouring right, it is still not clear under what circumstances a work is a computer-generated work. With the increasing application of artificial intelligence (AI), the copyright controversies associated with computer-generated works have become even more complicated. This chapter focuses on policy and legal issues surrounding the output of AI and copyright protection of computer-generated work under the Copyright, Designs and Patents Act (CDPA) 1988 in the UK. The CDPA approach to computer-generated work deviates from the mainstream international copyright practices, where human creativity is essential for authorship and copyright protection. From a policy perspective, it is important to explore whether this deviation can be justified. This chapter also investigates authorship issues concerning computer-generated works based on case law and its application, in particular who the person making the necessary arrangements is, and what the necessary arrangements in the AI environment are. Other issues relevant to computer-generated work, such as copyright term and joint authorship will be analysed as well.

Methods for resolving the Braess paradox in the presence of autonomous vehicles

Roads are a shared resource which can be used either by drivers and autonomous vehicles. Since the total number of vehicles increases annually, each considered vehicle spends more time in traffic jams, and thus the total travel time prolongs. The main purpose while planning the road system is to reduce the time spent on traveling. The optimization of transportation networks is a current goal, thus the formation of traffic flows by creating certain ligaments of the roads is of high importance. The Braess paradox states the existence of a network where the construction of a new edge leads to the increase of traveling time. The objective of this paper is to propose various solutions to the Braess paradox in the presence of autonomous vehicles. One of the methods of solving transportation topology problems is to introduce artificial restrictions on traffic. As an example of such restrictions, this article considers designated lanes which are available only for a certain type of vehicles. Designated lanes have their own location in the network and operating conditions. This article observes the most common two-roads traffic situations, analyzes them using analytical and numerical methods and presents the model of optimal traffic flow distribution, which considers different ways of lanes designation on isolated transportation networks. It was found that the modeling of designated lanes eliminates Braess’ paradox and optimizes the total traveling time. The solutions were shown on artificial networks and on the real-life example. A modeling algorithm for Braess network was proposed and its correctness was verified using the real-life example.
