Accurate forecasting of thermal loads is a critical factor for operating district heating and cooling networks economically, efficiently with minimized emissions. If are known high accuracy in advance, use renewable energies can be maximized, fossil generation, particular peaking units, avoided. Machine learning has already proven to an efficient tool time series this context. One recent advanc...

To provide a reference for the renovation of Shanghai’s existing residential districts, this study quantifies and compares relationships between common strategies, microclimate, heating cooling loads. These strategies include improving greening rate (G), reflectivity pavement (P), wall materials (W), roof or applying green (R). are applied to typical model extracted from areas in Shanghai, Chin...

Single-switch quasi-resonant DC inverters are preferred in low-power induction-heating applications for their cheapness. However, they pose difficulties enforcing soft-switching and show limited controllability. A good design of these converters must proceed parallel with the characterization load operating conditions. The control switching frequency has a critical relationship to non-linear be...

Induction heating (IH) is a process of the electrically conducting materials especially ferromagnetic with help electromagnetic induction through generating heat in an object by eddy currents. A well-entrenched way IH to design system pertaining usage such as stainless steel, iron, etc., which restricts end user’s choice using utensils made only. This research article proposes new scheme that e...

ABSTR&CT Seven brickmaking clays from various geological horizons have been studied by differential thermal and X-ray methods. The minerals detected included kaolinite, illite, montmorillonite, chlorite, swelling chlorite, calcite and quartz, and rough estimates were made of the quantities present. For the same clays, deformation-under-load was measured at four different heating rates, and stre...

A low cost fiber-optic micro-cavity interferometric sensor is presented. The micro-cavity is fabricated at the fiber tip by splicing a silica capillary to a single mode fiber and then heating/melting the capillary to form a microsphere with an internal air cavity. Applications of the micro-cavity sensor for temperature and traverse load measurements are demonstrated. The sensor has small size a...
