AN ANALYSIS OF NEIGHBOURHOOD TYPES FOR POINTNET++ IN SEMANTIC SEGMENTATION OF AIRBORNE LASER SCANNING DATA
Authors: Akbulut Z. , Ozdemir S. , Karsli F. , Dihkan M.
Published: March 2024

Abstract. The objective of the study is to conduct a comprehensive examination of how different neighbourhood types, namely spherical, cylindrical, and k-nearest neighbour (kNN), influence the feature extraction capabilities of the PointNet++ architecture in the semantic segmentation of Airborne Laser Scanning (ALS) point clouds. Two datasets are utilized for semantic segmentation analysis: the Dayton Annotated LiDAR Earth Scan (DALES) and the ISPRS 3D Semantic Labelling Benchmark datasets. In the experiments, the kNN method exhibited approximately 1% higher accuracy in weighted mean F1 and intersection over union (IoU) metrics compared to the spherical and cylindrical neighbourhood types on the DALES dataset. However, in the generalization experiment conducted on the ISPRS dataset, the spherical neighbourhood achieved the best results in these metrics, outperforming the cylindrical neighbourhood by a small margin. Notably, the kNN method was the least accurate, with a decrease in accuracy of approximately 1% in both weighted mean IoU and F1 scores. These findings suggest that the features extracted from spherical and cylindrical neighbourhood types are more generalizable compared to those from the kNN method.

Published: March 2024

Abstract. Amidst the rising prevalence of electric vehicles (EV) and the corresponding need for adequate charging infrastructures, this study presents an innovative application of deep learning models to analyze urban traffic. Utilizing the YOLO v3 model, our research focuses on developing a prototype for counting vehicles at an urban roundabout connecting three main roads, providing essential data for planning EV charging infrastructures. This work involves adapting and optimizing the YOLO v3 model to accurately identify and count vehicles passing through the roundabout. The aim is to measure traffic volume and identify circulation trends, which are crucial for understanding the spatial and temporal distribution of vehicles. The collected data not only estimate the number of EVs likely to traverse this area but also predict the needs for charging infrastructure in and around this specific roundabout. Our prototype demonstrated high accuracy in vehicle counting, allowing detailed analysis of traffic patterns at different times of the day. This analysis reveals significant variations in traffic flows, providing valuable insights into the most suitable times and locations for installing EV charging stations. While this study focuses on a single roundabout, it establishes a precedent for using advanced deep learning techniques in assessing EV charging infrastructure needs in broader urban contexts. The results suggest that such methods can be extended to other urban areas for more comprehensive and effective planning of EV charging infrastructures, thus contributing to more sustainable and intelligent urban mobility management.
Variational techniques for a one-dimensional energy balance model
Authors: Del Sarto Gianmarco , Bröcker Jochen , Flandoli Franco , Kuna Tobias
Published: March 2024

Abstract. A one-dimensional climate energy balance model (1D EBM) is a simplified climate model for the zonally averaged global temperature profile, based on the Earth's energy budget. We examine a class of 1D EBMs which emerges as the parabolic equation corresponding to the Euler–Lagrange equations of an associated variational problem, covering spatially inhomogeneous models such as with latitude-dependent albedo. Sufficient conditions are provided for the existence of at least three steady-state solutions in the form of two local minima and one saddle, that is, of coexisting “cold”, “warm” and unstable “intermediate” climates. We also give an interpretation of minimizers as “typical” or “likely” solutions of time-dependent and stochastic 1D EBMs. We then examine connections between the value function, which represents the minimum value (across all temperature profiles) of the objective functional, regarded as a function of greenhouse gas concentration, and the global mean temperature (also as a function of greenhouse gas concentration, i.e. the bifurcation diagram). Specifically, the global mean temperature varies continuously as long as there is a unique minimizing temperature profile, but coexisting minimizers must have different global mean temperatures. Furthermore, global mean temperature is non-decreasing with respect to greenhouse gas concentration, and its jumps must necessarily be upward. Applicability of our findings to more general spatially heterogeneous reaction–diffusion models is also discussed, as are physical interpretations of our results.

Alzheimer Hastası Bakım Vereninde Kişilerarası Psikoterapi Yaklaşımı: Olgu Sunumu
Authors: ARASAN DOĞAN İdil
Published: March 2024

Alzheimer's Disease, which is turning into a public health problem in elderly societies, is characterized by significant deterioration in cognitive as well as behavioral processes, and is defined as a neurodegenerative disease, has a challenging process, especially for caregivers. The caregiver, who is seen as the main decision-maker in the disease, may experience problems with both the patient and the environment due to the burden of care, lack of knowledge about the disease, and the weakness of support networks. While the caregiver tries to manage the disease process, they also face loss and mourning. For this reason, especially the difficulty in accepting and adapting to changing roles brings about conflicts in relationships with the patient and others. At this point where support mechanisms gain importance, the Interpersonal Based Psychotherapy (IPT) Approach, which will be put into practice constructively, has a positive impact on caregiver relationships and makes the process bearable by reflecting positively on the prognosis of the disease. IPT is a psychotherapeutic approach used on many interpersonal problems and psychiatric syndromes, and works on the areas of interpersonal conflict, grief and loss, and role reversal. This case study aimed to evaluate the IPT Approach for D., who was caring for his father with Alzheimer's Disease. It has been seen that the approach plays an effective role when the caregiver's relationship with the patient and others is evaluated. Observed in literature studies is that positive interventions for caregivers have positive effects on both the patient and the caregiver. Olgu D., who experienced conflict in her relationships due to the weight of the burden of care and existing life responsibilities, along with the diagnosis of her father's illness, gained accurate information about the disease. At the same time with the therapeutic approach, the insight gained as a result of strengthening the support mechanisms, explaining the situation and the need for help, and the positive structuring of the social support network were achieved.

Published: March 2024

Field experiments were conducted to determine the biometric and mechanical properties of onion crop relevant to component designs of machine for its harvesting. The percentage distribution of the onion bulb below the ground surfaces indicated that 94% onion bulbs were within 6 cm depth. The plant length of onion crop ranged from 11.0 to 32.0 cm, with a mean of 17.76 cm, at row-to-row spacing of 14 cm. The average value of equatorial diameter for small onion was 34.5 mm and polar diameter was 33.8 mm, where as these values for medium and large size onion were 49.82, 41.41 and 64.68, 53.20, respectively. The average weight of onion bulbs with leaves were 21, 52 and 112g for small, medium and large sizes and the bulk density was 180, 260 and 290 kg.m-3, in the same order. This helped in estimating the amount of material handled by the elevator of onion digger. The information could be used to design different components of an onion digger.

Published: March 2024

Groundwater recharge from two different water conservation structures under humid conditions of eastern ghat high land (EGHL) zone of Orissa were estimated by employing water table fluctuation procedure. A power function relationship best fitted the recharge and water storage depths. Contribution of base flow was segregated from the recharge values using base flow hydrograph separation technique. Potential groundwater recharge based on four years (2004-07) was estimated in the range between 3.5 - 11.0 % of the annual rainfall while considering the runoff contributing area of the conservation structures. Temporal groundwater contour maps generated using grid based graphics SURFER package (Version # 8) and GPSMAP (Version # 76CSX) for the study watershed revealed that there was a total net increase of 8.12 m and decrease of 2.61 m water table depths during wet and dry periods, respectively, resulting in net increase of water table by 1.38 m per year due to the influence of the water conservation structures. Groundwater quality of the wells in the watershed was found to be safe for irrigation and domestic consumption purposes.
Long-term Use of Saline Drainage Waters for Irrigation in Subsurface Drained Lands: Simulation Modelling with SWAP
Authors: A. K. Verma  , S. K. Gupta  , R.K. Isaac
Published: March 2024

SWAP (Soil-Water-Atmosphere-Plant) version 2.0 was evaluated for its capability to simulate crop growth and salinity profiles for a saline water irrigated area (Sampla, District Rohtak, Haryana) having shallow water table provided with a subsurface drainage system. Canal water (0.7 dS.m-1) was used for pre-sowing irrigation in all the treatments and thereafter, canal (0.7 dS.m-1), mixed canal and saline drainage water of varying salinity (6, 9, 12 dS.m-1) and drainage water alone varying in salinity from 12 to 27 dS.m-1 were used for irrigation. Absolute deviations and standard error between the SWAP simulated and the observed relative yields during calibration ranged from 2.6 to 7.2% and 3.1 to 9.7%, respectively, and established the validity of SWAP model under the experimental conditions. The scenario building simulations carried out with the validated SWAP revealed that yield at a higher level could be sustained with subsurface drainage than without it. Optimum yields in most years could be obtained with irrigation water of EC dS.m-1. It was established that notwithstanding the seasonal build-up of salts due to saline water use, there would be no long-term build-up of salts as leaching during the monsoon season would render the soil profile salt free at the time of sowing of rabi crops. SWAP was found to be a useful tool to assess the performance of subsurface drainage systems with reuse of saline drainage water for crop production.

A study was conducted to determine the effect of blanching on moisture adsorption and desorption characteristics of spinach. Moisture sorption was determined by gravimetric method. Different saturated salt solutions were prepared to provide constant relative humidity environments. Four spinach samples (unblanched, unblanched dried, blanched and blanched dried) were kept at 3 temperatures (300C, 400C and 60ºC) with corresponding 5 relative humidity levels (10.95 to 92.31%). It was observed that for all samples, equilibrium moisture content (EMC) of spinach increased with increase in relative humidity at constant temperature. At constant relative humidity levels, EMC decreased with increase in temperature. The adsorption EMC of the spinach was lower than the desorption EMC for blanched as well as unblanched spinach for all temperature and relative humidity ranges. The blanched dried spinach exhibited lowest EMC at all temperature and relative humidity ranges.

Published: March 2024

An experiment was conducted at PAU Regional Station, Bathinda, to study the impact of different spacing of surface drip lines and irrigation levels (0.6, 0.8 and 1.0 PET) on cotton growth and yield. The results revealed that cotton yield and water use efficiency (WUE) under drip was significantly higher than conventional flood irrigation. Maximum yield was achieved under drip line for each row of crop with irrigation level of 0.8 PET, whereas WUE was recorded for the same drip line spacing, but at 0.6 PET irrigation level. The initial growth (as reflected by leaf area index) was retarded for drip line in between two rows of crop as compared to drip line for each row of crop, but the rate of growth were similar for all drip line spacing after 45 days of sowing.
Nutritional Water Productivity and Global Food Security
Authors: Nawab Ali
Published: March 2024

Water is life and is one of the major inputs for agriculture. Earth has a finite supply of fresh water and therefore, demands that every drop of annual rainfall should be conserved and judiciously utilized for production and post- production agriculture to get maximum nutrients per unit of water. The concept of water productivity in agriculture is now shifting from harvest index per unit of land and water to nutrients (protein, carbohydrate, fat, etc.) produced per unit of water. This varies with food commodities and locations. For example, the total dietary energy produced by potato, maize, peanut, wheat, milk, egg and beef using one m3of water are about 5600 kcal, 3800 kcal, 2300 kcal, 2280 kcal, 660 kcal, 520 kcal and 100 kcal, respectively. Similarly, the production of protein using one m3 of water by potato, peanut, maize, wheat, egg, milk, chicken, and beef are 150 g, 111 g, 77 g, 74 g, 41 g, 40 g, 33 g and 10 g, respectively. This paper describes the water nutrient productivity of some of the crops and livestock products and suggests as to how to provide food and nutritional security through an appropriate and balanced diet design, to the maximum number of people of the world from the limited and dwindling land, water and bio resources.

Published: March 2024

Lucerne seeds were pelletized using a developed seed pelletizer. The seed pelletization process was standardized using locally procured gum arabic solution (20%) in water as binding material for coating materials like pond clay, sand, neem leaf powder, biogas plant spent slurry powder. Pelletization efficiency was greater than 90% in most of the cases in a range of 84-92%. Sphericity ranged from 0.80 to 0.89. The pellet sphericity, bulk density and 1000 pellet mass increased with duration of pelletization. The unpelleted seeds did not fulfill the required criteria of the Indian Minimum Seed Certification Standard of minimum germination per cent of 80. The fresh and dry mass of germinated seedlings was more in the pelleted seed compared to unpelleted seed. The use of 100% pond clay, with pelleting for 30 min, resulted in pellets giving higher germination (89%) and vigour index.

Case report: Posterior arm perforator flap for reconstruction of axillary defect after infected radiation-induced ulcer
Authors: Minh Pham Ngoc
Published: March 2024

Axillary soft tisue defects are uncommon in Vietnam. We report a case of an 81-year-old female patient had an infected axillary skin ulcer after going through a radical surgery and radiation therapy 30 years ago. In this case, a CT scanner was used to evaluate the fundus of the lesion and biopsy to rule out malignancy. The treatment procedure was eliminating infection based on the antibiogram, wound care, debridement, negative pressure wound therapy and reconstruction of defect. The optimal choice in this case was to use posterior arm perforator flap. After the surgery, the flap had a good vitality and the wound healed after 3 weeks. The case affirmed that the posterior arm perforator flap is suitable for axillary coverage and should be considered as one of the main options for axillary reconstruction.
Steatohepatitic hepatocellular carcinoma: Two cases report with literature review
Authors: Huyen Dao Thi
Published: March 2024

Steatohepatitic hepatocellular carcinoma (SH-HCC) is one of the most common hepatocellular carcinoma (HCC) subtypes, with a frequency of 5-20%. These tumor are well-differentiated and show distinct histologic features resembling steatohepatitis: Macrovesicular steatosis, inflammation, balloon cells, Mallory-Denk bodies and pericellular fibrosis. Because of their similar characteristics, distinguishing SH-HCC from background fatty liver can be a diagnostic challenge. The histology of SH-HCC has been described in resection specimens. Unfortunately, diagnostic criteria to aid in the evaluation of biopsy specimens have not been well established; therefore, the diagnosis of SH-HCC in biopsies remains challenging. On diagnostic imaging tests, SH-HCC may be difficult to distinguish from surrounding liver parenchyma in patients with severe hepatic steatosis or other fat-containing liver lesions such as angiomyolipoma or clear cell HCC. We report two cases of SH-HCC that we documented along with diagnostic difficulties.

Authors: Ha Nguyen Thu
Published: March 2024

A 14 year old girl diagnosed with primary biliary cirrhosis, gastrointestinal bleeding, and esophageal varices underwent an assessment of her nutritional status using SGA, BAZ (Body Mass Index for age), and MUAC (Middle Upper Arm Circumference). Prior to transplantation, her SGA score was categorized as C, her BAZ was -1.63 standard deviations, and her MUAC measured 18.5cm. Patients receive specialized care tailored to the different stages of their condition following transplantation. In the early post-transplant period, nutritionists employ a combination of enteral and parenteral nutrition. By the end of the first week after surgery, the patient's total energy intake reached 1582.7 kcal, with a protein intake of 1.7g/kg, and her SGA score improved to B. Starting from Day 21, protein and energy intake increased to 2.4g/kg and 30kcal/kg/24h, respectively. Upon discharge, the patient exhibited enhanced nutritional status, with an SGA score of B, a BAZ of -1.56 standard deviations, and a MUAC measurement of 20.0cm. She also experienced a weight gain of 1.5kg within one month of leaving the hospital. Consequently, the implementation of a Nutritional Management Plan, structured around the distinct stages of liver transplantation, is of paramount importance, particularly for pediatric patients.

Hybrid optimization model with Neural Network approach for renewable energy prediction and scheduling in large scale systems
Authors: Alvarez Gonzalo E.
Published: March 2024

Climate change demands clean energy solutions, and renewable sources such as solar and wind are prime candidates. However, their variability poses challenges for their integration into large-scale power systems. This paper addresses this issue by proposing a novel hybrid mathematical model. The proposal integrates both fossil and renewable sources, considering real-world constraints such as system demand, reserves, and transmission dynamics. The model combines several approaches. By using a novel block composition technique, the computational complexity is reduced, making the model applicable to large-scale systems. A neural network is also developed to improve the forecasting of renewable energy production, which is crucial for managing its intermittency. The effectiveness of the proposed model is tested by considering the large Argentinean electricity system, demonstrating its practical applicability. The results show that acceptable forecasts can be obtained for the generation and transmission scheduling of the whole system.

Published: March 2024

Introduction: Over the last Century, Thousands of studies were conducted to highlight the factors affecting warfarin efficacy and toxicity. Many of these studies had major limitations because they focused only on one or a few factors. Objectives: to determine the effect of 14 different clinical and genetic factors on the clinical outcomes (efficacy and toxicity) of warfarin in Egyptian patients with autoimmune diseases. The secondary objective was detecting the association between genetic polymorphisms of VKORC1 (rs 9923231) and systemic lupus erythematosus (SLE) susceptibility in the Egyptian population. Methods: after signing a consent form, 150 patients were included in the study from Kasr Aleiny Hospital, Cairo University. All medical records were reviewed to extract the effect of age, sex, diagnoses, genotypes, warfarin-drug interactions, and all patients' comorbidities on warfarin's efficacy and toxicity. The average warfarin doses, INR, (No. of times)/total times of INR within the therapeutic range, differences between the maximum and minimum INR values, the addition of enoxaparin and discontinuing warfarin and shifting to Rivaroxaban, and bleeding episodes were determined. Results: all the studied factors had clinical and statistical significance on the clinical outcomes. The T allele was associated with treatment failure and a shift to rivaroxaban, a higher risk of bleeding and SLE. Conclusions: Awareness of the effect of the factors addressed in this study is mandatory for the assessment of warfarin efficacy and toxicity for each patient. Further studies are essential in other specialties because different warfarin-drug interactions may be detected, with other comorbidities and on different genes.

The thermo-industrial human society is mainly based on fuels. Currently, societies are fully dependent on fossil fuels which cause climate change that threaten human race. Solar fuels are well suited technologies to face these challenges. Long-term solar energy storage based on chemical fuel production from water (and potentially CO2) has a significant importance to decarbonize our societies. Artificial photosynthesis is especially adapted to produce solar fuels, such as hydrogen, methane, ethanol, etc. This study focuses on hydrogen production. Water splitting with photolysis reaction is possible thanks to photocatalysts that absorb light and produce hydrogen. Modeling the hydrogen production is based on 3 main physics fields because the process is limited and controlled by radiative transfer. Electromagnetism is used to determine radiative properties. Then, radiative transfer allows to calculate photon absorption rates. Finally, the thermokinetic coupling law establishes a relation between photon absorption rate and hydrogen production rate. Experimentally, hydrogen production is operated in a dedi-cated laboratory-scale benchmark photoreactor. Photon flux density is controlled by a LED panel and hydrogen pressure variation is monitored with a pressure sensor. It is then possible to calculate experimental hydrogen production rates. The model predicts a non-linear thermo-kinetic coupling law, which fits well experimental results. Consequently, we demonstrated that the concept of incident solar flux density dilution is an important feature for process optimiza-tion. Several dilution technologies from TRL 3 to 5 are implemented in our laboratory thanks to the new PAVIN solar platform. They aim to validate high-efficiency technologies thanks to solar flux dilution.
