Hsuehshan tunnel which included two bore and three ventilation shaft systems is the longest (12.9 km) freeway tunnel in Taiwan. 56 species volatile organic compounds (VOCs) were sampled in two different locations each bore and three emitted shafts to determine the emission factors (EFs). Each sampling day has three sampling period: morning (8:00-10:00), Noon (12:00-14:00) and afternoon 16:00-18:00). C2 species were analyzed by GC/FID and C3 − C12 species were analyzed by GC/MS. The composition in southern bore was expressed by alkanes (36.69% − 39.20%), aromatics (34.14% − 36.33%), alkenes (20.27% − 21.95%), Alkynes (3.35% − 4.11%) and Naphthenes (1.06% − 1.35%). Northern bore had the similar profile. Ethylene (4.93 ¡Ó 2.21 mg/veh-km), Isopropane (4.85 ¡Ó 2.75 mg/veh-km), toluene (4.55 ¡Ó 1.31 mg/veh-km), m,p-xylene (2.98 ¡Ó 0.90 mg/veh-km) and propylene (2.70 ¡Ó 0.88 mg/veh-km) are the top five abundant VOCs in southern bore ; Isopropane (6.78 ¡Ó 3.33 mg/veh-km), ethylene (5.44 ¡Ó 2.63 mg/veh-km), toluene (5.32 ¡Ó 2.39 mg/veh-km), propylene (3.55 ¡Ó 1.67 mg/veh-km) and m,p-xylene (3.36 ¡Ó 1.45 mg/veh-km) are the top five abundant VOCs in northern bore. The EFs were smaller than other freeway tunnel investigated. Shaft emitted the partial mass of VOCs result in concentration gradient dropped off. The total VOCs EF of shafts during holidays was in the range of 72.24 mg/s − 180.60 mg/s higher than on weekdays in the range of 53.40 mg/s − 82.74 mg/s. The EF of shafts had effected by air-extracting apparatus, so standard deviations (S.D.) varied widely. Combining the EF of shaft with EF of tunnel we obtained the overall vehicle EF which was close to other freeway tunnel results. The proportion of Ozone formation potential (OFP) in both bore were alkenes (47.5% − 48.5%), aromatics (40.2% − 42.3%) and alkanes (9.8% − 10.1%). Note that sum of alkenes and aromatics exceeded 90%.

A análise por matriz de transferência é utilizada para obter as freqüências naturais do sistema, considerando-o sem amortecimento, e movimento em órbita circular. Realizou-se uma fase experimental, a fim de se verificar a teoria desenvolvida, bem como observar os modos de vibrar do disco, do eixo, e do sistema disco-eixo, e suas respectivas freqüências naturais. / The main objective of this work is to investigate the resonant frequencies of rotors, taking into account not only the flexibility of the discs, but also the bending moment (due to the gyroscopic effect) applied to the shaft. The theorical analysis is based in the transfer matrix technique. The system was assumed to be undamped with the shaftdisc in circular orbit motion. An experimental work was carried out in order to obtain the mode shapes and the natural frequencies of the disc, shaft, and of the disc-shaft system. A good correlation was observed between the theorical and experimental results. Keywords: resonant frequencies, flexibility of the discs, disc-shaft system, transfer matrix method.

Diploma thesis deals with a new built multifunctional building in Brno on Mlynska street. The intention is to change of use of lucrative corner site brownfield. The new building has four aboveground floors and one underground floor. The ground floor will have small restaurant and two separated shopping units. The second floor is divided into three office spaces. The third and fourth floors are designed as flats of different categories. The underground floor will be used for storage spaces, boiler room with separate pellet storage and parking shaft system. Construction system is designed as a wall construction system made of sand-lime bricks. Ceiling constructions and staircases are designed as a cast-in-place concrete. The building is roofed with the flat green roofs and terrace, which will be used for relaxation of residents.
