การออกแบบเครื่องแต่งกายที่สะท้อนสีสันของธรรมชาติโดยศึกษาการดึงดูดของสนามแม่เหล็กจากดวงอาทิตย์และโลกผ่านแสงแห่งออโรร่า

The purpose of this fashion thesis is to study the characteristics of the light color and the shape of the light of Aurora and designed the work to be novel interesting by showing the design of the ladys style costume by using the light color characteristics of Aurora a color scheme that can be combined with the technique of clothing editing binding. Dyeing batik making in costume design That makes the consumer look new unique more beautiful. The tools used in this study Is an aurora light analysis model. The sample used in this study is a photograph of Norwegian photographer Ole Christian Salomonsen. The criteria in the analysis are 2 aspects which are 1) Body 2) Color and overall analysis to be used Creative costume The results show that the aurora outline and color light is caused by charged particles in the space passing through the Earths atmosphere releasing energy in the form of light in which different colored light characteristics occur. The light curtain that you see has various shapes such as helical scrolls. Flutter wave tear streak or all three forms Applied to the costume design by paying attention to the style of the dress and the selection of various techniques including Fabric overlapping tie dyeing Batik making suitable for clothing styles for creating new and unique costume designs that meet the needs of consumers.

Nowadays Thailand is realizing the economic value of earthworms. Earthworm farming is a driving force that can stimulate the Thai economy. The objective of this project is to measure the humidity and temperature properties of the worms the two boards are circuit boards in microcontroller. These are the WeMos D1 ESP8266 board and NodeMCU ESP-32S board. The WeMos D1 ESP8266 board to measure the amount of water and temperature of of the soil and can turn the water supply on or off automatically. The NodeMCU ESP-32S board has a database system to collect real-time humidity and temperature data. The data is processed and displayed via a web interface. The experiment showed that in regard to earthworm farming the soil moisture alert system in the earthworm closet has a temperature accuracy of 28.5°C. The top soil has a humidity accuracy of 65% the middle soil has a humidity accuracy of 67% and the lower soil has a humidity accuracy of 67%. This allows the ideal moisture and humidity levels for the propagation of earthworms to be maintained. The alert system displays the temperature and humidity in the earthworm closet and can turn the water supply off if the soil moisture level gets too high for the worms - this can all be monitored via the web application. .

Using of ethylenediaminetetraacetic acid (EDTA) and synthetic surfactant increase the chemical contamination in water. The co-phytotoxicity of EDTA (0-20 mg/l) and 3 synthetic surfactants; Triton X-100 (0-10xCMC) Tween 80 (0-10xCMC) and sodium dodecyl sulfate (SDS) (0-2 x CMC) on the growth of 2 duckweeds spirodela polyrrhiza and Lemma perpusilla were studied for 3 days. The results showed that the surfactant were phytotoxic on the growth of both plants while EDTA was not. SDS was the most toxic to plant especially on all chlorophyll content. Triton X-100 was only toxic to the growth of L. perpusilla and weight of S. polyrrhiza. Tween 80 was less or the least toxic to both plants. This surfactant only decreased chlorophyll a and total chlorophyll content of S.polyrrhiza and L. perpusilla. There was not any interaction between EDTA and surfactant on most toxicity tests. With these results synthetic surfactant contamination should be more concerned than co-contamination with EDTA.

This study applied the kunzelstab penetration Test (KPT) or Light Penetrometer to examined penetration resistance values geological profiles and estimate shear strength properties of soils. KPT tests were carried out on steep slopes that exhibit potential slope movement in Chiang Rai province. The principal uses of the KPT are examined; i.e. correction method for N’KPT’ soil profile and allowable bearing capacity of soil foundation. KPT tests were conducted at 13 boreholes each measuring 4.00 m long along the crown of the slope. The results indicated the compacted layer and located the firm layer of soil foundation. The average allowable bearing capacities were 1.53 t/m2 at depth of 1.00-5.00 m and 17.06 t/m2 for 5.00-6.00 m depth respectively. Furthermore this paper presents an analysis of the stability of a slope with the shear strength parameters of the soil and the geological profile were defined based on the results of KPT. The results of factor of safety were below the stable value for analysis cases with groundwater table. Test results demonstrate the usefulness of the KPT method in geotechnical investigations to estimate soil profile and bearing capacity efficiently and economically. This approach is also less time consuming compared to other geotechnical site investigation methods.

This research aims to study the Mirai Botnet working process which made high bandwidth impacted to Internet system. From 90000 clients of Deutsche Telekom cannot access to Internet that overall bandwidth growth nearly 1 TB per second in the history DDoS attacking behavior. As Mirai exaggerated attacking to ISPs and may be involved UniNet as a big umbrella which RMUTP network interconnected as well. The author would like to study in depth to several weak points of the end devices or IoT on Internet. In the Mirai code used the IoT devices such as the Internet cameras the CPUs based on ARM ARM7 Motorola 6800 SPC PowerPC X86 and SuperH (SH4). As the results of valuable attacking code studied based-on IPV4 attack without IPV6. The source code has more than 5500 lines with 16 files and 138 functions included 62 set of user accounts and passwords. Usage the 9 flooding techniques for port attacking via 22 23 and 80 with the IP scanning exceptions for DoD IANA GE and HP IP addresses. The Internet camera devices have to disable 22 23 and 80 ports or doing suitable usability techniques to manage for several flooding protection from system harmfully.
