An improved ARX model for hourly cooling load prediction of office buildings in different climates
Authors: Fan Chengliang , Liao Yundan , Ding Yunfei
Published: July 2018

An attempt was made to develop an improved autoregressive with exogenous (ARX) model for office buildings cooling load prediction in five major climates of China. The cooling load prediction methods can be arranged into three categories: regression analysis, energy simulation, and artificial intelligence. Among them, the regression analysis methods using regression models are much simple and practical for real applications. However, traditional regression models are often helpless to manage multiparameter dynamic changes, making it not accurate as the other two categories. Many of the existing cooling load prediction studies use piecewise linearization to manage nonlinearity. To improve the prediction accuracy of regression analysis methods, higher order and interaction terms are included in improved ARX based on traditional ARX model. The improved ARX model consists of eight variables, with eleven coefficients accessed at a time. For applications and evaluations, an office building in major cities within each climatic zone was selected as a representation. These cities were Harbin, Beijing, Nanjing, Kunming and Guangzhou respectively. The coefficient of determination R2 is greater than 0.9 in five cities. The prediction results show that the improved ARX model can adapt to different climatic conditions, including those nonlinearity cases.

Depth estimation has achieved considerable success with the development of the depth sensor devices and deep learning method. However, depth estimation from monocular RGB-based image will increase ambiguity and is prone to error. In this paper, we present a novel approach to produce dense depth map from a single image coupled with coarse point-cloud samples. Our approach learns to fit the distribution of the depth map from source data using conditional adversarial networks and convert the sparse point clouds to dense maps. Our experiments show that the use of the conditional adversarial networks can add full image information to the predicted depth maps and the effectiveness of our approach to predict depth in NYU-Depth-v2 indoor dataset.

Authors: Chen Pengyu , Kong Ying
Published: July 2018

Luanchuan County, located in the mountains of Western Henan Province, is characterized by poor geological environment and abundant material sources and rainfalls. Debris flows have occurred many times in this county, and in some gully debris flows exhibit a large scale, requiring risk assessment. In the multi-factor comprehensive assessment methods for debris flow risk, it is really important to determine the weight of each factor since this affects the reliability of the assessment results. Given that the subjective weighting method can accurately reflect the importance of each factor, in order to improve the reliability of subjective weighting, the group decision making method is used to determine the weight of each factor. Group decision making is realized using the analytic hierarchy process and the data fusion algorithm. In this method, the expert combination weight is determined; on this basis, a model for comprehensive assessment of debris flow risk is established by the linear weighted sum method, and risk assessment is performed for gullies with medium to large-scale debris flows in the study area. The assessment results show that all debris flow gullies face minor to moderate risks. For gullies with high risk degree, it is suggested to timely clear material sources in channels and construct or reinforce retaining dams in order to prevent re-occurrence of debris flows.

Authors: Chi Luo-jia , Feng Xin-xi , Miao Lu
Published: July 2018

For the problems that Gamma Gaussian Inverse Wishart Cardinalized Probability Hypothesis Density (GGIW-CPHD) filter cannot accurately estimate the extended target shape and has a bad tracking performance under the condition of low SNR, a new generalized labeled multi-Bernoulli algorithm based on Gaussian process regression is proposed. The algorithm adopts the star convex to model the extended target, and realizes the online learning of the Gaussian process by constructing the state space model to complete the estimation of the extended target shape. At the same time, in the low SNR environment, the target motion state is tracked by the good tracking performance of the generalized label Bernoulli filter. Simulation results show that for any target with unknown shape, the proposed algorithm can well offer its extended shape and in the low SNR environment it can greatly improve the accuracy and stability of target tracking.

Authors: Ma Jiajia , Che Chao , Zhang Qiang
Published: July 2018

The contradiction between the large population of China and the limited medical resources lead to the difficulty of getting medical services. The emergence of question answering (QA) system in the medical field allows people to receive timely treatment at home and alleviates the burden on hospitals and doctors. To this end, this paper proposes a new model called Att-BiRNN-Att which combines the Bidirectional RNN (Recurrent Neural Network) with two attention mechanisms. The model employs BiRNN to capture more information in the context instead of the traditional directional RNN. Also, two attention mechanisms are used in the model to produce better feature representation of the answer. One attention is used before the input of BiRNN, and the other is used after the output of BiRNN. The combination of two attentions makes full use of the relevant information between the answer and question. The experiment on the HealthTap medical QA dataset shows that our model outperforms four state-of-theart deep learning models, which confirm the effectiveness of Att-BiRNN-Att model.

The measured capacitances by ECT system are usually normalized at the high and low permittivity for image. Parallel normalization model is commonly used during normalization process, which assumes the distribution of materials in parallel. And thus, the normalized capacitance is a linear function of measured capacitance. The usage of series normalization model results in the normalized capacitance as a nonlinear function of measured capacitance.

Published: July 2018

The traditional recognition method takes the low-level information of the image as the foundation. The image recognition center of gravity is biased towards the typical features, and achieves the effect of recognition by region-dependent segmentation. Because the general image segmentation is a regular rectangle, easily lead to the same target is divided into different sub-blocks, ignoring the image of the fuzzy part, so the image recognition is not complete. An image recognition algorithm based on threeway decision is proposed. It takes full advantage of effective information in the image, improving the image recognition accuracy. First, this method divided the image into three regions: positive region, negative region and delay decision region. Second, an iterative process is performed on the region of the delay decision. Final, image recognition is performed on the positive sample region. Based on the basic theory of the three-way decision, the more obvious the decision result is, the more iterations are, and the information is added to the classifier until the blurred part of image cannot be divided. Finally, to achieve the realize effective image recognition. This method simulates the process of human cognition effectively, and makes the utilization of the effective information reach the maximum in the recognition process. The results of the experimental analysis showed that the method is more concise and efficient, and the recognition accuracy is more accurate.

Authors: Fan Yao , Liu Wenxiang , Xiao Wei , Sun Guangfu
Published: July 2018

When using RDSS positioning under elevation constraints, traditional positioning accuracy estimation methods may not reflect the impact of satellite ranging error and elevation error on positioning performance accurately. In order to evaluate RDSS positioning performance more accurately, the RDSS positioning principle is presented, and the weighted position dilution of precision (WPDOP) is used to replace the traditional algorithm. The positioning error calculated by WPDOP is closer to actual results, indicating better prediction capability of positioning performance. Under different elevation error conditions, the position dilution of precision (PDOP) distribution of the service area indicates that the difference between the two precision factors is mainly affected by the elevation error and latitude, while the influence of longitude is small.

Published: July 2018

Software as a Service(SaaS)has become a mainstream way for enterprises and governments to promote informatization. However, it is very easy for users to change their SaaS supplier due to low implementation costs. Improving user satisfaction with SaaS products and ensuring their continued usage by users present practical challenges that SaaS suppliers cannot ignore. The traditional information system success model only pays attention to the quality of products which is known as internal quality. This paper combines the internal quality features of SaaS with the suppliers’ quality and environmental quality. These two qualities constitute external quality, which also affect user satisfaction. The study comprehensively explores the impact mechanism of SaaS user satisfaction based on the integrated perspective of internal quality and external quality. We use SPSS23.0 and SmartPLS to examine the hypothesis with data from 212 valid questionnaires. The study finds that system, information, service, supplier, and environmental quality have a significant effect on user satisfaction, and the influence of service quality is the greatest.

Background Obesity could be considered as the main consequence of unhealthy nutrition, responsible for many pathological alterations in human. Obese patients usually need more health care services. The aim of the study was to estimate the financial expenditures of health care provisions in Hungary, related to obesity and diabetes, as its main pathological consequence.

Methods Data of the Hungarian National Health Insurance Fund (NHIF) were collected for 2013, regarding finances of secondary care, hospital services, reimbursement for medications and healing aids of diabetic patients together with selected morbidities linked to obesity, based on the codes of the International Classification of Diseases (ICD) and calculated their population prevalence on the population-attributable fraction (PAF).

Results Financial data regarding diabetes care resulted in a 40,311 Million HUF (129 Million EUR) national fund expenses, beside a 7,173 Million HUF (23 Million EUR) contribution from patients. Estimated total health care expenditures related to obesity were 58,986 Million HUF (188 Million EUR) and the financial contribution of patients was calculated as 25,316 Million HUF (81 Million EUR). These data represent a 5.2% and 9.3% of the whole national health services, 16% and 30% of the whole drug-reimbursement budgets, respectively.

Conclusions Although expenditures for some obesity related pathologies analyzed in this paper represent 0.28% of the national GDP, considering other morbidities and other patient’s expenses, the real ratio could be between 0.5–1%. The increasing number of overweight and obese persons requires more focus in public health, higher awareness in the society and more governmental support.

Purpose Diabetes mellitus (DM) and carpal tunnel syndrome (CTS) are common pathologies. The diagnosis of CTS can be facilitated by the use of an ultrasound-based wrist-to-forearm ratio (WFR) of the nerve diameter. However, the applicability of WFR in DM-patients is not yet clear.

Materials and Methods 233 wrists of 153 patients were examined. Cross-sectional areas (CSA) of the median nerve were obtained using a linear array probe. The WFR was calculated.

Results Diabetics with CTS had significantly lower WFR values than non-diabetics with CTS (p = 0.002). There was no difference between the WFR of diabetics with and without CTS (p = 0.06). The diagnostic accuracy between diabetics with and without CTS was low for measurements of WFR (ROC AUC = 0.630, 95 % CI 0.541 – 0.715, p = 0.011).

Conclusion Our findings suggest that the WFR has a low diagnostic accuracy in diabetic patients with CTS and should be used with caution in those patients.

Purpose Homocysteine is associated with cardiovascular, inflammation and autoimmune diseases. Previous studies have shown that thyroid peroxidase antibody is associated with homocysteine levels in hypothyroidism. The relationship between thyroid antibodies and homocysteine in hyperthyroidism remains unclear. In this study, we aimed to investigate the association of thyroid antibodies with homocysteine in patients with Graves’ disease.

Methods This was a cross-sectional study including 478 Graves’ disease patients who were consecutively admitted and underwent radioiodine therapy. Homocysteine, thyroid hormones, thyroid antibodies, glucose and lipids were measured.

Results Patients with homocysteine levels above the median were older and had unfavorable metabolic parameters compared to patients with homocysteine levels below the median. Thyroglobulin antibody or thyroid peroxidase antibody was associated with homocysteine levels (β=0.56, 95%CI 0.03-1.08, p=0.04; β=0.75, 95%CI 0.23-1.27, p=0.005). The relationship between thyroid peroxidase antibody and homocysteine remained significant when additionally adjusting for free triiodothyronine (β=0.76, 95%CI 0.24-1.28, p=0.004). The presence of a homocysteine level above the median increased significantly with increasing thyroid peroxidase antibody quartiles in the logistic regression (OR=1.74, 95%CI 1.27-2.39, P for trend=0.001). Homocysteine levels increased significantly with increasing thyroid peroxidase antibody quartiles (p=0.005). Thyroid peroxidase antibody had no significant effect on other traditional cardiovascular risk factors.

Conclusions Thyroid peroxidase antibody is independently and positively associated with homocysteine levels in patients with Graves’ disease. Thyroid peroxidase antibody may be associated with the cardiovascular risk of patients with Graves’ disease through its effect on homocysteine.

Thrombomodulin, TM, is an endothelial cell membrane protein acting as a cofactor for the activation of plasma protein C. Soluble TM is present in plasma and urine of normal subjects. Enzyme immunoassay, EIA, for human TM was developed using mouse monoclonal antibodies against human placental TM in this paper. We obtained four types of the monoclonal antibodies against human placental TM. EIA sandwich method using three types of the monoclonal antibodies enabled us to measure almost all of 6 and 7 TM subspecies in plasma and urine, respectively, except 1 subspecies, 31 kDa TM. There was no interference from other components of plasma and urine in the assay conditions. Titration curves of purified TM in buffer or in normal plasma were linear within the range from 0.08 to 10 ng/ml. The coefficient of variation at 0.08 ng/ml TM was 4.7%. TM titer with buffer, assayed by this method, was reduced by the addition of thrombin at the final concentration of 20 U/ml, but the titer with plasma was not reduced even at 100 U/ml. These concentrations of thrombin are far larger than those which would be formed in circulation. TM levels in plasma and urine of normal subjects collected in the morning were 35.2 ± 8.32 ng/ml (n = 346) and 111 ± 31.6 ng/ml (n = 33), respectively. TM level in plasma did not differ from the level in serum. Circadian fluctuation of plasma TM was not significant in 10 normal adults, although a tendency of increase in TM excretion to urine was found rather in the day time than the other times. It was concluded that this EIA is reliable for TM assay in human plasma and urine, which will reflect activation or injury of endothelial cells.

Antithrombotic potency of recombinant hirudins rHV2, rHV2–Lys47 and rHV2–Arg47 was studied in a model of experimental thrombosis induced by tissue factor in the rat. Venous thrombosis was induced by i.v. injection of 25 mg/kg tissue factor followed by stasis of the inferior vena cava. In this model natural recombinant hirudins, rHV2 and rHV2–Lys47 injected 5 min before thromboplastin totally inhibited thrombosis in the same μg range as heparin or natural hirudin extracted from leeches. However, the mutant variant rHV2–Arg47 gave a maximal 60% inhibition of thrombosis. Variants rHV2–Lys47 (30 μg/kg) and rHV2–Arg47 (157 μg/kg) injected 5 min before thromboplastin prevented by 90 to 100% the drop in platelet count observed during the disseminated intravascular coagulation induced by thromboplastin injection. Recombinant hirudins were less anticoagulant than heparin as measured by an APTT on rat plasma. After rat tail transection, rHV2–Lys47 caused a 2–fold smaller prolongation of the bleeding time than an equivalent antithrombotic dose of heparin. Plasmatic elimination of rHV2–Lys47 from rat plasma after i.v. injection had a fast distribution phase with a half-life of 3 min during which 90% of injected rHV2–Lys47 was lost and was followed by a slower elimination phase. Thus recombinant hirudin rHV2–Lys47 appears as a promising potent antithrombotic agent for the prevention of thrombin-dependent venous thrombosis and disseminated intravascular coagulation
