Abstract:
Much development work and scientific research has been conducted in recent years in the field of detecting human activity and the measurement of biomechanical performance parameters using portable sensor technologies, so-called wearable systems. Despite the fact that boxers participating in one of the most vigorous and complex disciplines of all sports, it is one of the disciplines where no noteworthy, advanced performance analytic tools are used for training or for competition purposes worldwide. This research aimed to develop and validate a comprehensive punch performance sensor system for t

Abstract:
Martial arts has many benefits not only in self-defence, but also in improving physical fitness and mental well-being. In our research we focused on analyzing the velocity, impulse, momentum and impact force of the Taekwondo sine-wave punch and reverse-step punch. We evaluated these techniques in comparison with the martial arts styles of Hapkido and Shaolin Wushu and investigated the kinematic properties. We developed a sensing system which is composed of an ICSensor Model 3140 accelerometer attached to a punching bag for measuring dynamic acceleration, Kinovea motion analysis software and 2

Abstract <strong>&nbsp;</strong> Employee engagement is a critical factor influencing organizational performance, attracting attention from researchers and practitioners. It encompasses affective, cognitive, and behavioural dimensions, shaping employee&rsquo;s commitment and productivity. Theories like social exchange and self-determination explain its antecedents, including leadership style, organizational culture, job characteristics, and well-being. Human resource practices such as recruitment, training, and performance management play a vital role in fostering engagement. Engaged employees

Abstract:
An integrated micropress was developed for ultrafine piercing of metallic foils by a SiC fiber punch. The fiber punch was produced by a series of processes that use buffing and electrolysis operations. The technology incorporates unique tooling and fixturing techniques to handle delicate pinholes, apertures, collimators, and air slits to allow a repeatable manufacturing process with minimal part handling. Since the diagnostic pinholes may be very thin or small in size, it is critical that there is minimal human intervention from the start to the final process of the piercing operation. Selecti

Abstract:
The small punch test (SPT) can be very convenient to obtain mechanical properties due to its unique advantages from small-volume samples, and has gained wide popularity and appreciation among researchers. In this paper, the SPT test and finite element (FE) simulations were performed for three alloys, and the yield stresses (σYS) and ultimate tensile strengths (σUTS) from the uniaxial tensile test (UTT) were correlated with the yield force (Fy) and maximum force (Fm) of the small punch test (SPT) before and after compliance calibration. Finally, the effect of specimen size on the SPT curves was

Results are reviewed collected in the investigations of periodic contact and mixed problems of the plane, axially symmetric and spatial elasticity theory. Among mixed problems, cut (crack) problems are focused integral equations of which are connected with those for contact problems. The periodic contact problems stimulate research of the discrete contact of rough (wavy) surfaces. Together with classical elastic domains (half-plane, half-space, plane and full space), we consider periodic problems for cylinder, layer, cone and spatial wedge.

Abstract:
Dermatofibrosarcoma protuberans (DFSP) of the breast is an infrequent soft tissue sarcoma that usually affects young to middle-aged women. Our case report describes a unique occurrence of DFSP of the breast in an adolescent girl, which was initially being managed as a keloid for 2 years under dermatology despite being refractory to treatment. Once the diagnosis of DFSP was confirmed through punch biopsy, our patient underwent surgical excision of the lesion under general anaesthesia. Our patient was at an increased risk of damage to the ductal system due to proximity of the lesion to the nippl

Cost-effective noise reduction techniques for historic buildings can be accomplished affordably and without altering the structure's historic status. Techniques include adding sashes to existing historic windows, replacing windows with visually compatible acoustic units, and using jamb extensions to accommodate manufacturers' standard window units. Wood-truss roofs can be insulated from noise on the interior through the addition of a light-gauge metal framing support with alternating layers of gypsum board, plywood, and batt insulation.

Abstract. Transplanting seedlings is one of the most important but labor-intensive operations in strawberry cultivation. However, oversized strawberry seedlings, the planting environment of elevated cultivation facilities and the requirement of positioning the arched back outward are unique challenges compared with current transplanters for other plants. First, we investigated the working environment and goal of the transplanter. In this research, a new system was proposed that is completely different from existing transplanters.

The main objective of this research is to identify optimal printing strategies and PLA (polylactic acid) filament materials to produce rapid prototype deep drawing tools. Additive 3D printing technologies have been applied for a long time to produce tools, but the research is unique in that it uses conventional and various reinforced PLA materials with conventional FDM (Fused Deposition Modeling) printers. The advantage of this method is that PLA is easy to print and recycle and does not require expensive or special printers, this also gives the article its novelty. A further aim was to produc

Abstract Departure from explosive-based perforating methodology, coiled tubing (CT) abrasive jetting offers a valuable alternative for perforating. This technique employs fluids containing abrasive material, which are jetted at high pressure through a nozzle, creating a clean passage connecting the wellbore to the reservoir without causing perforation damage. Sand is the preferred abrasive material in the traditional methods as it causes significantly less damage to CT and jetting tools compared to more abrasive artificial solids like bauxite or ceramics.

Abstract The oil and gas industry is still in transition due to uncertain oil prices. The lower demand in oil production has become a key challenge for oil and gas companies to drill new wells.

Artificial lift systems (ALS) is the most efficient technique to optimize production from the well. The main purpose of artificial lift systems is to maximize production from a candidate well.

Incremental forming is nowadays increasing its presence in industry as a new but interesting process, especially for production of small batches or unique components. Anyway, relevant efforts have to be spent in order to reduce the typical incremental forming processes drawbacks that risk to belittle the high advantages in terms of costs and simplicity. In fact, the process duration, usually equal to several minutes even if the operations are carried out on high speed numerical controlled units, and a certain tendency to produce no precise parts, can reduce industrial interest about incrementa

The spray deposition system was used to deposit nanoparticles on substrate foils, which were consolidated to synthesize the multilayer composite. A patterned mask was used to create micro-pat

Many components in conventional and nuclear power plant, aero-engines, chemical plant etc, operate at temperatures which are high enough for creep to occur. These include plain pipes, pipe bends, branched pipes etc; the manufacture of such components may also require welds to be inserted in them. In most cases, only nominal operating conditions (i.e. pressure, temperatures, system load etc) are known and hence precise life predictions are not possible. Also, the proportion of life consumed will vary from position to position within a component and the plant. Hence, non-destructive techniques a

Abstract This work presents experimental studies on a new tool concept to address casing-casing-annulus (CCA) pressure leak challenges in the drilling industry. The new method uses an intervention-type tool that allows for exiting the casing, cleaning cement behind, and injecting any required sealant to block fluid migration on the annular side. Addressing such CCA challenges is essential for increasing the production time and maintaining wellbore pressure integrity. A combination of 3D modeling and experimental studies is used to evaluate the feasibility of the new concept for addressing CCA
