Roadway Floods And Their Associated Weather-Related Conditions: New Insights Using Cars 511 Data For State And Federal Highways In Nebraska, Usa, Logan R. Bundy, Mark Anderson, Clinton M. Rowe, Rezaul Mamood

Department of Earth and Atmospheric Sciences: Faculty Publications

This study examined roadway flooding event data provided by the Nebraska Department of Transportation via the Condition Acquisition Reporting System (CARS) 511 archive (2016–2021). With these data, a novel analysis was completed to further the understanding of where, when, and why (meteorologically) roadway flooding occurs on Nebraska state and federal highways. In the study period, 298 roadway floods occurred, with an annual median of 16 per year. There was a greater risk for roadway floods to transpire more frequently in eastern Nebraska, which was attributed to the spatial climatology of heavy rainfall and the higher density of roadways and rivers. …

A Critical Review Of Risk Matrices Used In Water Safety Planning: Improving Risk Matrix Construction, Kaycie Lane, Steve E. Hrudey

Department of Civil and Environmental Engineering: Faculty Publications

Risk matrices are used in water safety planning to prioritize improvements to drinking water systems. While water safety plans (WSPs) are promoted globally, no study has evaluated whether risk matrices are comprehensively constructed to accurately assess risk. We used risk matrix criteria adapted from previous risk matrix research to evaluate risk matrices found in twelve templates across global jurisdictions. WSP templates were found using the WSPortal website and definitions of likelihood and impact were extracted from each template to assist in the evaluation of WSP risk matrices. Application of the criteria developed from a detailed mathematical analysis by revealed that …

UBT International Conference

This article discusses the impact of using nano-alumina (NA) in micro-steel fiber-reinforced self-compacting geopolymer concrete (SCGPC) based on calcined kaolin clay (CKC). Three SCGPC mixes were created using NA in 1%, 2%, and 3% ratios as a partial replacement for CKC, while another mix without NA was also produced. All mixes had a constant total binder amount of 484 kg/m3 and a fixed quantity of micro-steel fibers of 0.5% by volume. The fresh characteristics were assessed by slump flow, V-funnel, and L-box tests. Additionally, the study assessed the compressive and flexural strengths, porosity, and water absorption at 28 days after …

Leaching Properties Of Fly Ash From Duvha Power Station In South Afric, Jabulani Veloso De Matsimbe, Megersa Melo De Dinka, David Caetano Olukanni, Innocent Oliveira Musonda

UBT International Conference

Fly ash and phosphogypsum are abundantly available in South Africa. However, landfilled industrial waste materials interact with the environment leading to groundwater, air, and soil pollution. This study aims to determine and quantify the heavy metal concentrations in fly ash from the Duvha power station and compare the results with US EPA regulatory limits. The TCLP and ICP-MS methods are used for leachate measurements. The results showed that the fly ash can be considered non-hazardous since the amounts of toxic elements such as Hg, Pb, Cu, Cd, Zn, Ni, As, P, Co, Se, and Mn are below the US EPA …

Distance Protection And The Importance Of Precision Measuring Equipment, Qendresa Syla

UBT International Conference

As we know short circuits are an inevitable phenomenon for the electrical power system. These damages must be quickly detected by the relay protection system and the damaged part must be isolated quickly. The defense of a line is of particular importance. When a defense system is designed, a compromise must be made between economics and performance, independence and security, complexity and simplicity, accuracy and speed.

From a technical point of view, the correct performance of the relay protection has been of particular importance over the years. It is not desirable for a node of the system to be taken …

Evaluating The Impact Of Demand-Side Response In Kosovo During The Energy Crisis: What Can We Learn?, Arven Syla, Avni Alidemaj, Martin Patel

UBT International Conference

The energy crisis in Europe due to war between Ukraine and Russia has led to a unprecedented situation. The volatility in gas supplies and prices has driven the wholesale electricity prices to increase enormously. Fortunately, this crisis has prompted many European countries to prioritise energy sector and advance green agendas. While the efforts to mitigate the energy crisis has primarily focused on the supply side (i.e., subsidies to energy suppliers), less attention has been paid to the demand-side. In this study, we examine how Kosovo managed the electricity crisis and consider the impact of demand-side. We analyze the data of …

The New Epbd Directive A Case Study Of A Renovation Of A Country House In Kosovo, Kliton Bylykbashi, Besar Veseli, Visar Krelani

UBT International Conference

With the "green houses" directive, the European Union intends to reduce GHG emissions by 55% to 2030 compared to 1990 levels and achieve zero emissions by 2050. Reducing emissions of polluting gases and fighting global warming are two objectives of the utmost importance for Europe, pursued through a policy that encourages the ecological transition. One of the most discussed interventions in this sense is the so-called Green Homes Directive or the EPBD Directive which aims to gradually eliminate buildings with inadequate energy performance by promoting the redevelopment of energy-intensive buildings. How can Kosovo respond to this objective at this moment? …

UBT International Conference

The objective of the research was to experimentally examine the corrosion of steel fibers in two media: a solution containing potato dextrose and calcium chloride (S1) (nutrient of the biological agent Oomicetum Pythium aphanidermatum that facilitates the self-healing of cementitious matrices), and water (S2). The corrosion process was accelerated by the Cebelcor method for 15 days, with immersion/emersion cycles of 5 and 19 hours, respectively. The results revealed that the corrosion of the fibers in solution S1 was 10.64% higher than that in S2. Regarding cross-sectional loss, the corroded fibers in S2 showed linear behavior, unlike those in S1, which …

Dynamics Of Simply Supported Beam Members Subject To Vertical Seismic Acceleratio, Francesco Foti, Luca Capacci, Bruno Dal Lago

UBT International Conference

Despite in most cases vertical seismic acceleration is disregarded in practical structural design, mainly due to the uncritical actions of the pertinent load combination, current standards prescribe the structural check of long-span and pre-stressed beam members subjected to vertical acceleration when they are located in high seismic hazard areas. Current design approaches focus on either finite element calculation, which does not provide a logical guidance to the designer for the problem, or, alternatively, on simplified calculations typically assuming lumped masses concentrated at midspan of the horizontal member. The latter approach does provide only an indicative solution affected by arbitrary modelling …

Assesment Of Bicycle Sharing Programs From A User Perspective: Kaybis, Hatice Göçmen Demir, Y .Kağan Demir, Anil Uruç
