The document presents research on modeling and analyzing the shear capacity of reinforced concrete beams made with steel fiber reinforced concrete (SFRC). Finite element models were created in ANSYS for plain reinforced concrete beams and SFRC beams. The models were validated against experimental test results. The following were found:

The document describes different types of shallow foundations, including spread footings, combined footings, and raft/mat foundations. Spread footings include wall footings, reinforced concrete footings, inverted arch footings, and column footings. Combined footings are used when columns are close together or near a property line. Raft foundations consist of a thick concrete slab covering the entire structure area and are used when soil capacity is low or loads are large. The document also discusses advantages, limitations, and construction procedures of shallow foundations.
Formwork is used to shape and support concrete until it gains strength. It can be made from various materials like timber, plywood, steel, aluminum, and plastics. Timber was traditionally most common but other materials are increasingly used. Different types of formwork exist for walls, slabs, columns, etc. Proper formwork construction involves propping, shuttering, providing chambers, cleaning, and surface treatment. Formwork must be removed carefully in the proper sequence once the concrete has gained enough strength. The type of material used depends on factors like cost, availability, and need for reuse.
Cast in situ piles are concrete piles that are constructed by excavating soil and pouring concrete directly into the hole. There are several types of cast in situ piles including simplex, franki, and vibro piles. The simplex pile is most common in Bangladesh. To construct a simplex pile, a casing is installed and reinforced with rebar before concrete is poured into the casing while it is vibrated out of the ground. Cast in situ piles are preferable to driven piles in areas with noise limitations, existing structures nearby, or weak and loose soils. The construction process involves soil testing, boring, installing rebar cages, and pouring concrete through a tremie pipe.

Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.

Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
