Understanding Determining Factors: Purchasing Decisions

Edit Süle Adrian Horváth Judit Bilinovics-Sipos

Publication Name: Lecture Notes in Mechanical Engineering

Publication Date: 2024-01-01

Volume: Unknown

Issue: Unknown

Page Range: 250-256

Description:

The paper aims to highlight the lack of usage of knowledge-based expert systems in purchasing decisions in the context of hybrid corporate reality. We use the transdisciplinary approach in our work, which is essential to examine the problem that occurs in the reality. While reviewing publications containing the keywords “Cognitive bias” and “Supplier selection”, we focused on the methods used. The examined methods in the pooled papers are mainly based on arithmetic and rank the possibilities without considering the available expert knowledge then and there. Afterwards, we propose a solution beyond analyzing the data measured in the past; in addition, the decision-maker, their mental model, and their knowledge is considered. We assume that the effects of cognitive biases are more readily identifiable when using expert systems in considering the decision-maker’s opinions in connection with the actually applied rules in making decisions. In addition to seemingly objective solutions, in our experiment, we propose that by using past cases with known results, complex rules, which are based on the expert’s knowledge, can be simplified without changing the results of decisions in purchasing.

Predictive hybrid scan-to-BIM method improves heritage building documentation completeness and accuracy

Kitti Karolyfi Nóra Géczy Rnin Salah

Publication Name: Scientific Reports

Publication Date: 2026-12-01

Volume: 16

Issue: 1

Page Range: Unknown

Description:

Incomplete survey data often undermines the reliability of Building Information Models (BIM), particularly for structures with restricted access and complex geometries. This study demonstrates a hybrid Scan-to-BIM workflow that integrates terrestrial laser scanning (TLS) and unmanned aerial vehicle (UAV) photogrammetry, supported by a predictive feasibility concept, to improve documentation accuracy and completeness. A two-phase strategy was validated on a chapel case study. Phase 1, combining TLS and ground-based photogrammetry, achieved only 54% coverage due to severe occlusions and limited scanner placement. These results led to the formulation of a Predictive Scan Feasibility Estimation Model (PSFEM), designed to generalize site-specific parameters such as scanner range, clearance angle, and building height into a decision-support tool for future surveys. Guided by the recognition of Phase 1 limitations, Phase 2 incorporated UAV photogrammetry and supplemental TLS, increasing coverage to 96%. Comparative analyses confirmed consistency in accuracy and improved geometric completeness. While the PSFEM was developed retrospectively based on the limitations identified in Phase 1, its analytical validation demonstrates the potential value of predictive planning for reducing redundant site visits and enhancing BIM reliability. The proposed framework provides a transferable basis for applying predictive hybrid workflows in both heritage and complex building documentation. This workflow offers a practical and scalable method for Scan-to-BIM documentation, applicable to heritage as well as other complex buildings, enabling high accuracy and completeness while effectively managing time and resources.

Application of laser-based photoacoustic spectroscopy and colorimetry for quantification of anthocyanin in hard boiled candy

Mihály Kovács Zsolt Ajtony Ottó Dóka Dane Bicanic

Publication Name: Microchemical Journal

Publication Date: 2017-11-01

Volume: 135

Issue: Unknown

Page Range: 100-104

Description:

The analytical performance of the newly proposed laser-based photoacoustic spectroscopy (LPAS) and colorimetric method for quantification of anthocyanin (E163) in commercially available hard boiled candies are compared to that of the spectrophotometry (SP). Both LPAS and colorimetry are direct methods that unlike SP do not require the extraction of the analyte or some additional sample treatment. Results indicate that LPAS and colorimetry are both suitable for quickly screening content of anthocyanin in hard boiled candies. The correlation between the two methods and spectrophotometry is linear with R2 = 0.9989 for LPAS and R2 = 0.9570 for colorimetry.

Publication Name: International Journal of Mental Health and Addiction

Volume: 23

Issue: 6

Page Range: 4600-4611

Description:

Exercise addiction has been investigated for almost half a decade in well over 1000 published papers. Studies adopt different terminologies like exercise addiction, overexercise, exercise dependence, compulsive exercise, obligatory exercise, and the like to refer to the same concept while creating conceptual confusion and rendering cross-study comparability challenging. The paradox is that fewer than ten research articles cover cases of clinical significance, yielding an extremely high ratio of publications to problematic cases. While there is evidence that significantly more clinically attention-meriting cases might exist, they surface in clinical practice rather than research settings. It is also peculiar that scholars search for a common path or shared etiology for exercise addiction, while each case, like those in substance use disorder, is unique, as also predicted by clinical models. Furthermore, the survey method uses scales yielding risk scores without diagnostic value. Most research in this direction, therefore, seems to be futile. Thus, it is not surprising that more than 10 years ago, the panel editing the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) found insufficient evidence for exercise addiction being a mental dysfunction. As a result, exercise addiction has no clinical diagnostic criteria. This position paper aims to identify conceptual and methodological research barriers that hinder progress in this field, ultimately calling for a paradigm shift toward more productive research. In conclusion, the position of this paper is that most currently used research methodologies on exercise addiction are unsatisfactory and, consequently, a paradigm shift is urgently needed.

Linear Quadratic Robust Control of Synchronous Reluctance Motor †

Zoltan Nemeth Dávid Gábor Bányai

Publication Name: Engineering Proceedings

Volume: 79

Description:

Synchronous reluctance motors (SynRMs) play a key role in modern vehicles as they do not require permanent magnets and sliding brushes, reducing maintenance requirements and increasing reliability. My research focused on the development of robust torque control for SynRM. In the simulations, I compared the linear quadratic (LQ) controller with the conventional proportional–integral (PI) controller. To apply the LQ control method, I converted the nonlinear motor model into a linear one. We expect the results of this research to show that the LQ controller provides faster and more robust performance than the PI controller. LQ control can provide faster response times and a more stable operation, which are particularly important under dynamic vehicle operating conditions. Although LQ control is more computationally intensive and takes longer to fine tune, the results show that it results in a better and more stable control system. Such benefits are significant in dynamic vehicle operating conditions where fast and reliable torque control is essential. Overall, it can be concluded that advanced control techniques such as LQ can contribute to increasing the efficiency and performance of synchronous reluctance motors in the automotive industry, thus contributing to the development of sustainable and reliable vehicles.

Assisting the passage of heavy vehicles, increasing traffic safety designing traffic lights and urban lighting in a smart city

Nikolett Fecser

Publication Name: International Journal of Heavy Vehicle Systems

Publication Date: 2024-01-01

Volume: 31

Issue: 4

Page Range: 562-578

Description:

Congestions caused by traffic bottlenecks or accidents have become commonplace. The consequences are delays, as well as environmental, health and economic damage. One of the solutions to the problem is to expand transport infrastructures and to apply and develop advanced control systems, as well as to create a public lighting network for new traffic routes and pavements. The capacity of the road section examined in this study is inadequate during peak hours, and significant queues are formed. Turning in a wide angle from the secondary direction to the left, especially with heavy vehicles is difficult and involves a risk of accidents. Due to heavy traffic, the intersection is to be controlled by traffic lights. In this study, the implementation of a traffic-engineering plan of a junction situated in Győr is presented with phase-timing plans. In the second part of the study, the results of measurements are described.

Description:

Objective: To validate the ISGPS definition and grading system of PPAP after pancreatoduodenectomy (PD). Summary Background Data: In 2022, the International Study Group for Pancreatic Surgery (ISGPS) defined post-pancreatectomy acute pancreatitis (PPAP) and recommended a prospective validation of its diagnostic criteria and grading system. Methods: This was a prospective, international, multicenter study including patients undergoing PD at 17 referral pancreatic centers across Europe, Asia, Oceania, and the United States. PPAP diagnosis required the following three parameters: (1) postoperative serum hyperamylasemia /hyperlipasemia (POH) persisting on postoperative days 1 and 2, (2) radiologic alterations consistent with PPAP, and (3) a clinically relevant deterioration in the patient's condition. To validate the grading system, clinical and economic parameters were analyzed across all grades. Results: Among 2902 patients undergoing PD, 7.5% (n=218) developed PPAP (6.3% grade B and 1.2% grade C). POH occurred in 24.1% of patients. Hospital stay was associated with PPAP grades (No POH/PPAP 10 days (IQR 7-17) days, grade B 22 days (IQR 15-34) days, and grade C 43 days (IQR 27-54) days; P<0.001), as well as intensive care unit admission (No POH/PPAP 5.4%, grade B 12.6%, grade C 82.9%; P<0.010), and hospital readmission rates (No POH/PPAP 7.3%, grade B 16.1%, grade C 18.5%; P<0.05). Costs of grade B and C PPAP were 2 and 11 times greater than uncomplicated clinical course, resp. (P<0.001). Conclusions: This first prospective, international validation study of the ISGPS definition and grading system for PPAP highlighted the relevant clinical and financial implications of this condition. These results stress the importance of routine screening for PPAP in patients undergoing PD.
